EXECUTIVE SUMMARY
'
The New York Power Authority has developed an alternative Inconel 82 temperbead weld
overlay welding approach which simplifies welding on reactor pressure vessel components.
1 his approach extends the temperbead welding concepts developed in a prior EPRI prograrn
so that reduced preheat can be applied to the low alloy steel component being repair
welded. This approach may allow for repair welding on these components without the.
necessity of dropping the water level in the vessel. The following items highlight the
Authority's qualification program.
* No deleterious change in mechanical properties or metallurgical structure
were observed when comparing the Authority's temperbead qualification
program to the industry and ASME Code accepted EPRI qualification
program.
* Other industry studies examining the use of no or reduced preheat or water.
O backins for the inco nei te m Perbeed w eid overiar su P r ort the A uthoriir -
welding approach that reduced preheat can produce a quality, weld cverlay
repair meeting the requirements of the ASME Code. *
e Potenthi adverse effects of reduced preheat welding on low alloy steel,
notably hydrogen embrittlement, have been investigated by others and have,
been determined to be of nc concern.'
* This subject remains a prominent research topic for EPRI and the utility
- industry as testing and evaluation continue to qualify and obtain ASME Code
acceptance for a reduced preheat temperbead welding process for low alloy
steel vessel and nozzle materials.

l.0 PURPOSE AND OBJECT'VE
O'The temperbead weld overlay repair involves welding with well controlled welding-
parameters to avoid high temperature (1100*F) post weld heat treatment. To perform a
temperbead weld overlay repair on a reactor vessel nozzle made of low alloy material the ;
recently approved ASME Section XI Code Case N432 [1] requires a 300'F preheat and
500'F post bake. Achieving these elevated temperatures requires draining the reactor vessel
which may cause significant outage schedule delays and high man rem exposures.
The Authority has embarked on a special weld overlay qualification program. The purpose
of this pr'ogram is to expand the temperbead weld overlay qualification concept to a wider
variety of repair conditions by modifying some of the welding parameters specified by the
Code for performing a temperbead repair. The Authority has qualified an alternative,
automatie gas tungsten arc (GTAW) Inconel 82 temperbead process, employing a 200*F
preheat and 500*F post heat, to the EPRI qualified Inconel 82 temperbead weld overlay
process which employs a 300*F preheat and 500'F post heat for use in repair of a low alloy
O stcei erguce a n atthe 3ames & Fitzre e k secieer e - er rient.
This report documents the results of the Authority's modified ter,perbead program and
summarizes the relevant work performed by industry leaders in qualifying reduced preheat
no post weld heat treatment weld overlay repairs.
The objective of this report is to provide the technical basis for requesting approval to
perform a weld overlay using a water backed 200*F preheat and no post bake.
The results of the NYPA temperbead weld overlay qualification program including the"
summary of relevant industry experience which addresscs technical issues regarding
temperbead repair weloing concludes the following:

The heat affected zone mechanical prciperties located in the low alloy base metal are*
not degraded by the application of a v eld overla', employing a 200*F preheat and
no post weld heat treatment.
Studies performed by other investigators that examined the use of no prehea'. or*
water backing for Inconel temperbead weld overlay confirm that the weld overlay has
little effect on the base metal notch toughness when compared to the unaffected base
metal nr the EPRI qualification process results.
The ytential effect of hydrogen embrittlement resulting from the reduced preheat*
arid no post heat has no harmful effect on the GTAW process.
The temperbead welding process produces residual tensile stresses on the surface*
which is welded and compressive residual stresses on the opposite surface. This
result leads to a more favorable through wall axial stress distribution which tends to
stop cracking.AV

Following a brief background and history of the evolution of temperbead weld overlay
repairs, this report describes the activities performed by the Authority to qualify a modified
Inconel 82 temperbead weld overlay repair which allows welding the overlay with reduced
preheat, thereby permitting water-backed welding.
The appendices contain, for easy reference, temperbead qualification work performed by
EPRI, CB&I, and Nutech, as well as material performed by Structural Integrity on pipe
residual stress after applying a weld overlay, and EPRI's evaluation of hydrogen
embrittlement during GTAW welding.

1.1 Background
r(
De use of the weld overlay for austenitic stainless steel piping as an intergranular stress
corrosion cracking (IGSCC) repair is widespread in the BWR industry. Originally the weld
overlay was designed as an interim measure, but extensive laboratory testing, analysis, and
field performance have demonstrated its suitability as a long term repair for stainless steel
piping. As a result of the extensive activity qualifying the overlay as a long term repair, the
Nuclear Regulatory Commission approved its use in NUREG 0313, Revision 2, [2]. In
addition, a Code Case has been introduced to Section X1 of the ASME Pressure Vessel
Code which would allow the overlay to be applied to stainless steel components without the
need for tase by case NRC review and approval as is presently required. This Code Case
has received a favorable endorsement by the utility industry and the jurisdictional and
regulatory personnel involved and is expected to be cdopted in the near future.
During the past several years, IGSCL has also been observed in Inconel 182 weld metal
associated with nonle cladding and noale butter, recirculation inlet and outlet nonles and
(l incore spray safe-end to nonle welds. IGSCCin inconel 182 weld metal has been reportedv
in domestic and foreign BWRs. The IGSCC associated with Inconel 182 in the nonle butter
at some plants also involved reported stress corrosion cracking which may have progressed
into the low alloy steel nonle material.
Recognizing the Incor,el 182 butter susceptibility to IGSCC in BWRs, an effort was
undertaken in 1985 to develop and qualify an inconel 82 weld overlay repair which could
be used to mitigate the consequences ofIGSCC in components containing Inconel 182 butter
or cladding. The project team for that program included the Georgia Power Company
(GPCo), the Electric Power Research Institute (EPRI), General Electric Company (GE) and,
1
Structural Integrity Associates (SI). The team performed the analysis, welding, metallurgical1
examinations, fracture mechanics, mockup evaluations, Code and licensing activities

carbon or low alloy steel component (P-1 or P-3 material) wanout a full post weld heat
treatment provided the requirements in the Code Case are met. This Code Case has (provided the basis for all temperbead Inconel 82 repairs which have been performed in
operating BWRs and has also been u;ed for Inconel 82 temperbead weld build-ups in
P%Rs.

One of the shortcomings of the EPRI temperbead study is that the required 300*F preheat
g and 500*F post bake result in the need to perform the repair with water removed from the
sicinity of the joint. This need can create scheduling and refueling problems. EPRI
recognized this short-coming and assembled a Temperbead Advisory Committee to
determine the technical feasibility of reducing the preheat and post bake to temperatures
which would allow the temperbead weld overlay to be applied with water in the pipe. The
Authority and Structural Integrity Associates, as well as the NRC are represented on this
EPRI Temperbead Advisory Committee.
In addition to the EPRI sponsored activities, other experimental studies have been
performed examining the effect of a reduced preheat or no preheat temperbead repair to
low alloy steel nozzle materials. The results of two of these studies are presented in this
report.
As presented in Section LO of this repcrt, the objective of the current New York Power
Authority study is to expand the temperbead weld overlay concept to a widet variety of
h repair conditions by modifying some of the welding parameters which were qualified in the
original temperbead weld overlay qualification program [3]. The parameters which were
ndjusted in this study are the preheat and the post weld heat treatment. As noted in the
preceding paragraphs, the original temperbead weld overlay qualiScation required a 300*F
preheat and a 500 F post bake. In this study, an Inconel 82 temperbead weld overlay was
qualific witt,1200*F preheat and no post weld bake. The incorporation of the 200'F
preheat w' ..o post heat treatment will allow the utilities a peiform the temperbead weld
overlay repair without draining any of the piping systems of water, thereby providing a
potentially significant reduction in outage schedule. Additionally, the presence of water in
the pipe can reduce the man-rem exposure associated with the repair and may provide
additional benefits to the repair, such as improving the inside surface residual stress
distribution when comp; red to a full post weld eat tretted safe-end to nozzle joint. Issues

such as unfavorable residual stress distributions, incomplete tempering of the low alloy steel- weld heat affected zone and hydrogen embrittlement effects were evaluated.
The following sections of this report describe the welding activities performed by the New
York Power Authority in qualifying a modified Inconel 82 temperbead weld overlay repair
which allows welding the overlay with reduced preheat, thereby permitting water backed

2.0 TECHNICAL APPROACH
O'2.1 New York Power Authority Temperbead Qualification Program
As described in Section 1 of this report, the objective of the Authority's program was to
qualify an alternative automatic gas tungsten arc (GTAW) Inconel 82 temperbead process,
employing a 200'F preheat and no post heat by comparing the results to the EPRI qualified
Inconel 82 temperbead weld overlay process, which employs a 300'F preheat and a 500'F
post heat, for use in repair of a low alloy steel nozzle application at the James A. FitzPatrick
Nuclear Power Plant. The approach used in this program was to procure two SA 508 Cl. 2
ring forg*ngs from the same heat of material in a size consistent with the recirculation inlet
nozzle (N 2 nozzle) at the FitzPatrich plant, perform the required post weld heat treatments
to simulate the heat treatment condition of the existing nozzles at the plant, and perform
the Inconel 82 temperbead overlay welding procedure on the ring forgings and machine
qualification test samples. The' certified material test reports for the ring forgings used in
this test program are presented in Appendix 1 of this report.
TNkj'
Three procedure qualification tests (PORs) were performed in accordance with Authority
weld proced. ire specification (WPS) NZ-Overlay. Two of the qualification tests were
performed to compare tiie lower preheat, no post bake temperbead approach to the EPRI
approach. -The third procedure qualification was of an actua' weld overlay using the EPRI
preheat and post bake parameters. WPS NZ-Overlay and the supporting PQRs (POR 395,
745 and 746) used to perform these qualifications are appended to this report as Appendix
2. One of the PORs, POR.746, was ud to deposit an Inconel 82 temperbead groove weld
in the ring forging (see figure in POR 746, Appendix 2). This temperbead groove weld,
deposited using a 300'F preheat and 500*F post bake in accordance with the EPRI
temperbead Inconel 82 qualification program [3], used welding parameters which_
approximated those used in the Reference 3 project. The principal difference between the
welding parameters in the EPRI welding procedures and in the Authority WPS NZ-Overlay
,

involved the arc voltage which was reduced by approximately 10% for the temperbead weld
overlay qualified in the program. This reduced are voltage, applied consistently as in the
Authority program, has no effect on the temperbead results.
The second POR, POR 745, was used to deposit an Inconel 82 temperbead groove weld in
the ring forging (see figure in POR 745, Appendix 2) with a 200*F preheat and no post'
bake using the same welding parameters as in POR 746 (WPS NZ-Overlay). This
temperbead weld represents the Authority alternative to the EPRI temperbead Inconel 82
weld overlay process.
The final weld, the demonstration Inconel 82 weld overlay weld, involving fabrication of a
simulated nozzle to safe-end mockup by welding a section of a ring forging to a Type 304
stainless steel simulated safe-end in accordance with Authority welding procedures employing
both automatic and manual welding techniques (GTAW and SMAW). A GTAW
temperbead Inconel 82 weld overlay was then applied to the simulated nozzle to safe-end
joint. The nozzle to safe-end mockup temperbead Inconel 82 weld overlay was welded in
'I accordance with WPS NZ-Overlay employing a 300*F preheat and 500*F post heat in.
accordance with the EPRI' qualification program [3]. Following welding, the weld was
sectioned and destructively examined as illustrated in the Physical Test Report for mockup
395 (Appendix 2), and the metallurgical and mechanical properties of the low alloy steel
weld ' heat affected zone were compared to the base metal properties for this nozzle to
safe-end joint.
The purpose of these tests on welded components is to determine whether the component
properties were degraded by welding. Section XI requires that repairs to components be
performed which result in the base metal being left in a state equal to or better than the
original as installed condition. Proper selection of weld metal can generally ensure that the
weld metal properties will meet or exceed those of the base metal which it is replacing.
However, tne weld fusion zone and the base metal heat affected zone can be adversely

i
affected unless careful selection is made of welding materials and welding parameters and )high quality welding is performed. The ASME Boiler and Pressure Code requires that, for
- heat treatable steels, of which low alloy vessel and nozzle steels are examples, appropriate
post weld heat treatment must be performed to ensure that mechanical properties of the
component are not degraded by the welding process.
The GTAW temperbead process simulates the post weld heat treatment metallurgical ]condition in the weld heat affected zone of a carbon or low alloy steel component by
judicious selection of welding heat input for each of the layers of the temperbead weld. The
EPRI/B&W program illustrates that using controlled welding parameters can produce a
suitably tempered low alloy steel metallurgical structure without post weld heat treatment
(4]. The EPRI Inconel temperbead study demonstrates that this automatic GTAW process
could be extended to an Inconel 82 weld overlay on a low alloy steel nozzle using an
automatic orbital welding technique [3].
WPS NZ-Overlay (Appendix 2) illustrates how the temperbead welding paremeters have
Q been selected to provide the metallurgical tempering and grain refinement normally obtainedV'
by a post weld heat treatment at typical temperatures of 1100 to 1300*F. One observes
from WPS NZ-Overlay that the welding heat input is quite low for the initial weld layer,
increasing in the secord layer and again in the third layer to allow the second and third
layers to temper and grain refine the low alloy steel heat affected zone beneath the first
weld overlay layer. The demonstration of this tempering effect on the low alloy steel heat
affected zone is obtained by ASME Code mandated mechanical property testing. The Code
| tests required for these heat treatable steels are tensile tests, bend tests, and Charpy V-notch
L impact tests. The tensile and bend tests evaluate the soundness of the weld metal and the
welding process. The impact tests examine the weld metal and the weld heat affected zone
comparing the results to the unaffected base metal. In subsequent test programs, EPRI has
demonstrated that increasing heat input with each temperbead layer not required. Rather,
! well controlled heat input will produce the required tempering effect.

2.2 Ir.dustry Developed Temperbead Qualification Prograrns
In addition to the EPRI qualification program (3) which the Authority used to develop--
parameters for its temperbead qualification program, other temperbead qualifications have
been performed by engineering organizations supporting the nuclear power industry. Among
the performed programs, two are particularly notable since preheat and post heat var 6d.
from the EPRI qualification program,in a manner similar to that performed in the Authority
program. These qualification programs were performed by Nutech, Inc. and by _CB&I )Services,Inc., and were reported at the EPRI Advisory Committee Meeting for Temperbead |
Welding held in Charlotte, NC, on November 2 and 3,1989. :
.
Sections 2.2.1 and 2.2.2 summarize the qualifications performed by these two organizations.
Detailed descriptions of these activities are presented in Appendices 3 and 4 of this report.

- OGenera! Public Utilities contracted Nutech, Inc. to develop a contingency plan for providing
an Inconel 82 temperbead weld overlay repair to a 26 inch diameter recirculation system
discharge nozzle at the Oyster Creek Nuclear Power Station. The temperbead repair was
identified as trie preferred approach compared to a full post weld heat treatment, since the
geometry of the nozzle end the physical space .:onstraint resulted in difficulty in'
accommodating preheat and post weld heat treatment equipment. Consequently, Nutech
developed procedures and performed qualification welds for both the temperbead weld
overlay approach developed in the EPRI program [3] and a modified temperbead approach -
in which no preheat or post heat were applied to the joint.

A 14-inch diameter nozzle was heat treated to simulate the post weld heat treatment
, condition of the discharge nozzle, buttered with inconel 182, and stress relieved at
1100-1150*F for one heur.
Following the stress relief heat treatment, a Type 304 stainless steel safe-end was welded to
the buttered nozzle using Inconel 182 manual welding techniques. Following the welding of
the safe-end to the nozzle, two additional grooves were machined into the nozzle for
temperbead welding in order to provide procedure qualification test samples. The
configuration of the nozzle to safe-end including the grooves for the procedure qualification
samples is presented in Figure 3 in Appendix 3. The procedure qualification temperbead
welding 6 performed by welding other temperbead welds including a weld overlay using
the EPRI 300'F preheat,500'F post heat technique (5 layers), then removing the preheat
and performing the water backed other one-half of the temperbead welds (5 layers) without
any preheat or post heat. The average temperature for the water backed welds was
70-75'F. Following the welding of the three temperbead welds as illustrated in Figure 3,
Appendix 3, the Code required mechanical tests and supplemental metallurgical tests wereOQ. performed. Results of these tests are presented in Appendix 3 of this report and are
discussed in Section 3.2.1 of this report.
2.2.2 CB&I Reactor Nozzle to Safe-end Temperbead Structural Overlay Test Program
The test program developed by CB&I Services, Inc., presents an ahernative to the EPRI
temperbead qualification [3] and affords utilities increased flexibility in performing a
temperbead repair to a low alloy steel nozzle to safe-end joint buttered with Inconel 182
weld metal. This test program, presented in Appendix 4, investigated the use of a non-water
backed, non-preheated, non-post heated condition and a water backed non post heated
condition as alternatives to the EPRI temperbead qualification [3].|

The CB&I program used an SA 508 Cl. 2 low alloy steel nozzle forging to perfonn the -
appropriate post weld heat treatment to simalate the vessel heat treatment, and to weld a
Type 304 stainless steel safe-end to the nozzle. Subsequent to the welding of the safe-end
to nozzle, a one inch deep groove was machined in the nozzle remote from the rozzle to
safe-end weld as illustrated in Appendix 4 and a six layer Inconel 82 temperbead weld was
deposited to fill the groove using a 300*F preheat and 500'F post heat to simulate the
EPRI temperbead process [3].
In addition to the temperbead groove weld, an Inconel 82 temperbead weld overlay was
applied to the nozzle to safe-end weld as a wet / dry overlay, using a partial thermal sleeve
(see Appendix 4 for details). With this configuration, one half of the nozzle at the safe-end
would be filled with water while the other half remained dry. This configuration allowed the
welding to be affected by a severe quench and a moderate quench. Neither preheat nor
post heat was applied to this joint. Following welding, Code required mechanical tests and
supplemental metallurgical tests were performed on the temperbead groove weld and the-
modified temperbead weld overlay. The results of these tests are presented in the Appendix

3.0 TEST RESULTS
3.1 New York Power Authority Temperbead Qualification Program
This section of the report presents the mechanical and metallurgical tests performed to
qualify the 200*F preheat, no post heat Authority Inconel 82 temperbead weld overlay for
low alloy steel nozzle to austenitic stainless steel safe-end welds (POR 745). The results of i
these tests are compared to the Inconel 82 te.mperbead weld overlay test results from the
EPRI por.sored program [3] and the results from the Authority simulation of the EPRI
qualification (POR 746) Finally, a simulued nozzle to safe-end Inconel 82 weld overlay
mockup was fabricated using the same welding parameters as POR 746, and the test results
for this mnckup are presented (POR 395) and compared to the EPRI qualification results.
3.1.1 Mechanical Property Tests
Professional Service Industries,Inc. performed all of the tensile and bend qualification tests
and for the metallurgical tests. The Charpy V-notch impact tests were performed by Lucius'
Pitkin, Inc. All physical property tests were performed in accordance with the ASME Code
requirements of Sections IX and XI and Code Case N-432. The physical test reports for
PORs 395,745, and 746 are included as Appendix 5 of this report, and the metallurgical
reports for the temperbead samples removed for the qualification welds are provided in
. Appendix 6. Tensile and bend test presented in Appendix 5 illustrate that acceptable results
were achieved for all samples tested. No defects were observed in any of the bend tests, and
the tensile specimens all failed in the weld at a stress level near the certified material test
report base metal tensile strength.
.Charpy V-notch impact tw were performed on weld metal, heat affected one and base
metal samples for each of the test conditions and were compared to the EPRI test results.
1 he heat affected zone Charpy samples for PORs 745 and 746 were oriented normal to the

weid so that the entire sample failure was in the heat affected zone. The base metal sample
was oriented the same way so as to make a direct comparison between HAZ and base metal
L/ . for these two PORs. Figure 1 in the Lucius Pitkin report for these two PQRs in Appendix
5 presents the orientation for these samples.
Tables 1 through 4 present the results of the Charpy V-notch impact tests for the three
procedures qualified in the Authority's program, comparing the results to the EPRI test
results for the HAZ and base metals at 40*F, the test temperature for the EPRI tests [3].
Table 5 is a summary of the average Charpy impact results for the three Authority
temperbead weld procedures and the EPRI procedure. All of the samples meet the 50 ft lbs
absorbed energy and the 35 mils lateral expansion required by ASME Section XI and Code
Case N-432. In all cases, the energy absorbed in the weld heat affected zones is greater than
the base metal absorbed energy. This result meets the mechanical property requirements
of the Code and of Code Case N-432 for the process to be qualified. No degradation of
physical property resulted from the 200'F preheat, no post heat treatment used in the POR
745 qualifiuition.

'"3.1.2 Metallurgical Tests
Metallurgical tests were performed to provide a direct comparison between the results of
these tests and the prior EPRI study [3]. The metallurgical tests involved microhardness
te.sts and metallographic examination of the weld heat affected zones for each of the
procedures qualified in this prsgram.
L The metallurgical tests were performed by Professional Service Industries, Inc. and are gD appended to this report as Appendix 6. Examination of the metallography for the 1
Authority's PQRs 395,745 and 746 revealed that the anticipated grain refinement occurred
| in the low alloy- steel weld heat affected zones for each of the procedures. The-
microstructural results are quite similar to those presented in Figures 3-8 and 3-9 of the

~ Reference 2 report. The base metal structure for these specimens appears to be a tempe ud
bainite or tempered martensite structure, the anticipated structure in this steel following' - quenching and tempering.
:
In order to confirm the tempering effect of the temperbead welding in the low alloy steel
heat affected zove, microhardness measurements were performed on the groove weld
samples in the Authority's qualification program (POR 745 and 746), and compared to the
EPRI groove weld qualification results using a 500 yam Knoop indentor traversing the weld
heat affected zone as was done in the EPRI study. The results of the traverses for the EPRI
groove weld sample [3] are presented in Table 6 and are compared to the Authority's POR
746 groove weld sample and the POR 745 groove weld sample in Tabler 7 and 8. Table 7
presents the actual Knoop data for the three traverses and Table 8 presents these data
converted to the Rockwell hardness scale. Examination of the Table 8 results reveals that
the hardnesses for the three procedures are quite comparable, within anticipated data
scatter, to a distance of approximately 1000 micr<ms (0.04 inches) from the weld fusion line.-
Beyond that point, the hardness in the EPRI sampb is significantly lower than for the two
] Authority samples, reflecting the fact that the base metel hardness of the EPRI nozzle was''
markedly lower than for the Authority ring forging. However, it is within the initial 1000
microns in the low alloy heat affected zone where high hardness due to improper tempering
may create a low toughness or embrittled joint. No such concern is observed from these
microhardness results.
3.2 Industry Developed Temperbead Qualification Programs
This section of the report summarizes the significant mechanical and metallurgical tests
performed in the Nutech and CB&l programs to qualify alternatives to the EPRI qualified
temperbead welding program (3]. These two alternative p:ograms qualified a water backed
temperbead procedure without preheat or post heat and a dry temperbead procedure again
without preheat or post heat treatment. In each case the results are compared to the EPRI

- qualification program results [3]. Detailed descriptions of the Nutech and CD&I programs |
are enclosed as Appendices 3 and 4 to this report.
3.2.1 Nutech Temperbead Qualification Program for Discharge Nozzle at the Oyster Creek
Nuclear Power Station
As described in Section 2 of this report, the Nutech qualification program compared an
Inconel temperbead weld overlay using the EPRI qualification program parameters [3] to
a temperbead weld overlay using water-bacxing and employing no preheat nor post heat
treatment. In addition to fabricating a weld overlay on a nozzle to safe-end mockup, two
groove welds were also fabricated to provide procedure qualificat.icn test samples comparing
the EPRI temperbead parameters to the water backed temperbead parameters. One of the
groove samples was welded in a part of the nozzle containing a 1/2 inch remaining wall
thickness beneath the groove (the 1/2 inch groove), and the other procedure qualification
test specimen was welded in a part of the nozzle with a 1-1/4 incil remaining thickness
beneath the groove. The two different thicknesses were examined to evaluate the effects
of location. Details of these tests are presented in Appendix 3 to this report and are~
summarized below.
Results of the tensile and bend tes.s for the procedure qualification welds illustrate no
unusual failures for any of the samples tested. No defects were observed in any of the bend
tests, and the tensile specimens all failed in the base metal remote from the weld heat
affected zone indicating that the temperbead welding had no deleterious effect on the tensile
results and bend test results.
Charpy V notch impact tests -were performed on the two procedure qualification weld
samples for the base metal and heat affected zones. Table 9 presents the results for both
the water backed (wet) and the " dry" 300*F preheat,500*F post heat temperbead groove
weld at the 1/2 inch and the 1-1/4 inch nozzle locations. Also included in Table 9 are the
SIR-90-063, Rev. 0 16gO

Charpy V-notch results for the base metal on the ". vet" and " dry" halves of the nozzle.
q These test results show that the absorbed energy and lateral expansion mee: the Codeb requirements of 50 ft-lb energy absorbed and 0.035 inches lateral expansion in all cases. The
impact energy absorbed and lateral expansion for the " wet" temperbead process are
generall lawer than that for the " dry" process. However, in the case of the heat affectedi
side samples, the " wet" properties are somewhat better than the " dry" results. One other
noteworthy result is that there is significant variability in properties in a nozzle forging. The
differences between the " wet" and the " dry" results at a specific location in the nozzle are
generally less than the differ nces in properties when comparing thinner and thicker
locations in the same no72.ie.
.
Table 9 also presents Charpy V-notch impact results for the weld overlay, using the EPRI
parameters (dry) for one half of the overlay and the water backed " wet" temperbead
parameters for the other half of the overlay. The weld overlay toe Charpy results in Table
9 illustrate that these results approximate the best base metal results in absorbed energy and
lateral expansion. Further, these results are essentially the same whether the welding was
O performed " wet," without preheat and post heat or " dry," with a 300* F preheat and a 500* FG
post heat treatment. The variability :n properties within the forging Lppears to dominate
the result obtained with the material notch toughness properties being far superior at the
outside surfax than within the forging. The implication of these results will be explored
further in Section 4 of this report.
3.2.2 CB&I Reactor Nozzle to Safe-end Tempe: bead Structural Overlay Test Program
The CB&l test program for the nozzle to safe-end is similar to the Nutech program. A
water backed " wet" overlay was qualified and compared to an overlay using the EPRI
qualification parameters [3]. However, the CB&l program contains an additional
qualification in which a " dry" temperhead weld overlay is applied to 1/2 of the nozzle to

safe-end joint without preheat or post heat. The results of this overlay qualification program
are presented below.'
Results of the tensile and bend tests for the procedure qualification welds show no unusual
failures for any of the samples tested. No defects were observed in any of the bend tests,
and the tensile specimens removed frorn the groove weld failed in the base metal remote
from the weld heat affected zone. Only all weld metal tensile specimens were evaluated for
the weld overlay specimens. The *. ensile and bend test results indicate that the temperbead
-welding has no deleterious effect on the mechanical properties for these temperbead
qualifiention welds, as illustrated in Appendix 4.
The Charpy V-notch impact results for the temperbe.ad groove weld welded using the EPRI
. qualification pararneters [3] are presented in Tab:e 10. These results illustrate that the heat
affected zone absorbed energy and lateral expansion are superior to the base metal results.
The Charpy V-notch impact results for the water backed temperbead weld overlay and the
dry temperbead weld overlay employing i o preheat or post heat treatment are presented
h in Tables 11 and 12. Also included in these tables are the corresponding base metal impact~
I test results repeated from Table 10. One observes from Tables 11 and 12 that the heat
affected zone notch toughness for both ginalification tests are superior to the base metal
properties in absorbed energy as well as in lateral expansion. No impact tests were
performed at the weld averlay toe regions for the water backed or dry qualification tests.
However, hardness te vs illustrate.J that full structural temperbead weld overlays covering
the nozzle to safe-end weld can be temperbead welded at the toe tie in points without the
use of filler- to obtain similar hardness and impact strength levels to that of the EPRI
; qualification (3).

4.0 DISCUSSION OF RESULTS
O ,
'
The results of the mechanical and metallurgical tests described in the prior section i
of this report illustrate that much research has been performed in developing and
qualifying alternative procedures to the EPRI qualified 300*F preheat,500*F post
- heat temperbead procedure for producing a weld overlay repair to a low alloy steel
nozzle to austenitic safe-end joint [3]. The Authority's process examined the effect
of a reduced preheat (200'F) and no post heat inconel 82 temperbead weld overlay .
repair process on mechanical and metallurgical properties of a low alloy steel nozzle
material..
The two groove weld procedure qualification tests performed in the Authority's
program, comparing the reduced preheat process (POR 745) to the EPRI process
(POR 746), demonstrated that little or no difference in mechanical or metallurgical
properties is to be expected when the preheat is reduced and no post heat is
performed. The slight differences in absorbed energy and lateral expansion between
the two processes fall well within the expected within lmat data scatter for impact
tests in this class of material.
This observation is confirmed by the Nutech and CB&l results in which a water
backed temperbead weld overlay is compared to the EPRI qualification results [3].,
In the CB&I case, Charpy V-notch absorbed energy and lateral expansion results for
the no preheat, no post heat procedure are superior to 'he unaffected base metal
results indicating that no deleterious effect would result from such a temperbead
overlay repair whether water backed or dry. The Nutech test results indicate that
both the wet and the dry temperbead groove welds produce heat affected zone
absorbed energy and lateral expansion which are reduced from the base metal results.
However, the actual temperbead weld overlay fabricated over the nozzle to safe-end-
weld produces absorbed energy which approximates that for the unaffected base

metal and the lateral expansion exceeds that for the base metal for both the . vet and
.O; the drx weid everier with ee nrcheet er nest heet treatment.
When comparing the water backed temperbead welding process to the dry
temperbcad welding process on the same heat of material using the same welding
parameters, the dry temperbead profess produce: somewhat improved toughness
results. However, this effect is less sig.tificant than the within heat variability in notch.
toughness which appears in each of :Se tests described in this program.
Th,e toughness of the as-fabricated and heat treated forging 's quite variable due ta
the metallurgy associated with this heat treatable material. Although this alloy is
designed for improved through-thickness hardenability, there remains a significant
variability in properties from the surface to the interior. The Nutech and CB&l base
metalimpact values illustra.e the through thickness variability in the notch toughness
of this class of steel. The outside suiface of the nozzle (or ring forging) always has
the best properties, since it is most rapidly quenched during component fabrication.
The fully quenched ma-tenait structure will always be tougher than a bainitic-
structure when properly tempered following the quenching. Therefore, this surface
-and the near surface region should have the highest notch toughness within the
component. Consequently, a temperbead weld overlay repair over this surface can
readily produce a significantly tougher structure than that of the base metalinterior.
This feature of a quenched and tempered low alloy steel provides added assurance
that the overall nozzle properties will not be degraded by a well controlled
temperbead weld repair. Of greatest importance, however, is that the base metal
- properties always met or exceeded the Code required 50 ft-lbs and 35 mils lateral
expansion at temperatures of 40*F or greater in the tcst programs described in this
report.

The previous discussions have illustrated that the use of reduced or no preheat, with
or without water-backing, can indeed produce an inconel 82 temperbead weld overlay'
repair on an SA 508 Cl. 2 low alloy steel forging which meets the Code requirements
for not'h toughness provided the welding is well controlled.
4,1 Additional Issues|
Additional issues were addressed providing further confidence that such a repair will
have no deleterious effect on the low alloy steel torging material. The issues are
hydrogen produced during welding, and the high residual stress due to the welding
of>eration. Both the hydrogen effect and the residual stress effect result from the
lack cf a post weld heat treatment.
4.1.1 Hydrogen
EPRI recently initiated a program to address the issue of hydrogen in SA 508 Cl. 2
( low alloy steel. The prograni involved preheating two sections of this material to
150*F and 300*F. Once the preheat was established, welding was initiated under
conditions of 95% humidity and a 120* F laboratory working temperature. Following
welding, the samples were prepared in accordance with the AWS Standard A4.3-86,
" Standard Methods for Determination of the Diffusable Hydrogen Content of a
Martensitic, Bainitic, and Ferritic Weld Metal Produced by Arc Welding." The results
of these tests are presented in Table 13.
The amount of diffusable hydrogen in t're sample preheated to 150*F was somewhat
lower than that produced during the 300* F preheat. Both diffusable hydrogen results
are at least one order of magnitude lower than the maximum allowed by the
Interr.ationalInstitute of Welding for acceptance as a hydrogen controlled weld when
welding mild and low alloy steels [5]. The results of this test program were presented

at the_ Temperbead Advisory Committee Meeting on October 30, 1990 and are
. included as Appendix 7 to this report. These results demonstrate that neither the_
150'F nor the_300'F preheat GTAW temperbead welding process will produce
-diffusable hydrogen in quantities which would produce a hydrogen embrittlement'
conceru in this alloy.
'
-This result is expected, since the bare wire GTAW process contains no obvious
source of hydrogen. There is no flux or coating which can be a source or hideout'
i
location for hydrogen as could be the case for the shielded electrode welding
processes.
I -
Residual Stress-
'
| 4.2'
| The issue of high tensile residual stress resulting from the welding operation is'
important to low alloy steel components. The ASME Code contains specific post
weld heat treatment requirements to address the residual stress issue and provides
e.:emptions depending on material hardenability and the restraint imposed by-
material thickness. The use of a well controlled welding process may reduce the size
of a heat affected zone thereby-limiting the extent of the residual stress field.
However, it is difficult to reduce or eliminate the peak residual stress caused by
melting of the base metal and resulting solidification shrinkage.,
In the case of a weld overlay, however,it is possible to use the residual stress effect,
|
|to an advantage. Since the weld overlay is applied to the outside surface of the
| component, opposite the surfa:.e which sees the aggressive coolant, one can use the
added heat sink effect associated with low or no preheat for residual stress'
redistribution. In the EPRI Inconel 82 temperbead weld overlay qualification 5
program, residual stress analyses were performed using finite element modeling to
| evaluate the effect of a temperbead weld overlay o- e state of ID stress in tne!-

nozzle and safe end in the vicinity of the butt weld [3]. In that study, a temperature
_h model was used to develop the transient temperature history due to welding. A
stress model using the temperature history as input, provided the residual stresses and
strains due to the temperbead welding, comparing the residual stresses of the butt
weld with those 4 the temperbead weld overlay..
The residual stress distribution due to the butt weld before the application of the
overlay is illustrated in Figure 1, taken from Reference 3. This figure shows that, as
a result of the relaively thick pipe wall modeled in this study, the inner surface of the
pipe and nozzle are under compressive axial and hoop stresses and the outer surface
of the pipe and nozzle are under tensile stress in the butt weld region. Residual
stress distributions after the application of the overlay are 3e 4mted in Figure 2 [3]
for the axial and hoop stresses. The weld overlay extends the compressive region for
axial residual stresses to almost the entire thickn-ss of the original pipe wall under
the overlay. The stresses at the ID surface are slightly less compressive following the
overlay compared to the residual stresses prior to the overlay application. However,
.. - the temperbead weld overlay significan:ly improves the through thickness residual'
stress state compared to the butt weld residual stress distribution. A lower preheat
would have little effect on the weld overlay distributions presented in Figures 1 and
2, because any reduction in preheat would be expected to produce an even more
favorable ID and through the pipe wall residual stiess distribution. Any increase in
the through wall temperature gradient would produce a more favorable ID residual
stress state, much as is observed-with heat sink welding and with the induction
heating stress improvement process.
The favorable residual stress improvement due to a weld overlay application stands
in marked contrast to a temperbead repair which is performed on the same surface
as is exposed to the aggressive coolant. In that case, the temperbead repair produces|
| ten;ile residual stresses in a location susceptible to stress corrosion cracking. In the

5.0 SUMMARY AND CONCLUSIONS
QThe New York Power Authority has developed u. alternative Inconel 82 temperbead
weld overlay repair method for low alloy steel components at the James A.
FitzPatrick Nuclear Power Plant. This temperbead welding approach provides an
alternative to the EPRI and the Code Case N 432 temperbead qualificationi
approach. In the Authority's qualification, a 200'F preheat, no post heat treatment j
temperbead welding approach is compared to the EPRI and Code Case N-432 |~
temperbead approach in which a 300'F preheat,500*F post heat treat weld was !
qualified. The results of the Authority qualification are summarized below,
The Authority's Inunel 82 temperbead wela overlay qualificatione
program demonstrated that the tensile, bend, and Charpy V-notch
impact properties of the SA 508 Cl. 2 low alloy steel heat affected zone -
are not degraded by the application of the temperbead weld overlay
employing a 200'F preheat with no post heat treatment. No
O. metallographic changes were noted in the Authority samp'n welded
with the lower preheat as compared to the Authority sample welded
in accordance with the EPRI temperbead parameters.
Studies performed by other investigators examining the use of no*
preheat or water-backing for the inconel temperbead weld overlay
support the Authority's observation that the lower preheat has little
effect on the notch toughness of these materials when compared to the
unaffected base metal or the EPRI qualification process results. In
some cases, the "no preheat" case produces superior notch toughness
as compared to the EPRI and Code Case N-432 parameters. In other
cases, the "no preheat" case produces somewhat lower notch toughness.
Although the notch toughness may be reduced slightly when using

,
water backing or no preheat during the temperbead welding, the within- heat variability in notch toughness properties in this class cf materials
is ' more significant than the lack of preheat during welding in
determining the Charpy V notch impact properties of these weldments
fabricated from SA 508 Cl. 2 low alloy steel. '
Reduction of the preheat from 300'F to 200'F and climination ofe
500*F post weld bake permit repairs to be made without dewatering
the pipe.. Significant reductions in outage schedule and decreased
radiation exposure to craft are potential advantages of the revised,
procedure.
The potential effect of hydrogen embrittlement resulting from thee
reduced preheat and no post heat has been investigated. For the
GTAW process, no deleterious effects of the reduced preheat are
noted. The amount of diffusable hydrogen within the low alloy ste:1'
following low temperature GTAW welding on SA 508 Cl. 2 is at least
one- order of magnitude less than that required for a hydragen
embrittlement concern.
The temperbead welding process on a low alloy steel component*
produces tensile residual stresses on the surface which is welded and
compressive residual stresses on the opposite surface. This result leads
to a more favorable through-wall axial residual stress distribution for
the temperbead weld overlay in which the cracking is initiated on the
surface opposite to that surface which is weld repaired. For weld
repairs to surfaces exposed to the aggressive environment, the tensile
residual stresses resulting from the temperbead repair must be
accounted for in the repair program.

In summary, the Authority, Nutech and CB&l qualification programs demonstrate
that an inconel 82 temperbead weld overlay repair can be applied to a low alloy steel=
nozzle with no or reduced preheat and no post heat treatment, without deterioration
of notch toughness of the SA 508 Cl. 2 steel properties. Any changes observed in
notch toughness are smaller than the within heat variability which exists in a typical
nozzle. Since the overlay is applied to the outside surface of the nozzle, opposite the
surface exposed to the aggressive coolant, no residual stress concerns or hydrogen
embrittlement concerns have been observed or are anticipated.<

concentrated in the stainless steel safe-end area rather than inthe no::le forging. This induction heat treatment is thougnt tohave no effect on the actual no::le properties in the regionstested. Please refer to the work orders in Appendix IV whichshow test specimen location.
The purpose of the test was threefold:
1. Produce a welding procedure qualification meeting the ASMECode Case N-432 which would establish base line materialproperties.
2. Produce a non-water backed and a water backed overlay which,when tested, the material properties could be comparea tothe base line established in the Code Case qualification. :
( ) 3. Provide sufficient technical data to allow in-servicen
repairs on no::le to safe-end welds by overlaying with and''
without water in the affected no::le/ safe-end.To do the comparison, a Code Case groove weld was made in oneregion of the no::le forging and a full thickness structuraloverlay was built-up across the no::le to safe-end joint. Theoverlay was blended smoothly into the 45 slope region of theno::le forging. Please refer to Appendix II for the no :leassembly drawings for details. As the Code Case requires the
procedure qualification to be done utilizing the equipmentplanned for the repair, the use of fiberoptic video monitoringwas used to produce both the groove and overlay welds.
Code Case N-432 Groove Weld.;
A 1" deep, 60 , with a .25" root opening groove was machined 360in the nozzle forging after trimming excess material from theno :le forging and PWHT for 24 hours at 1150 F plus or minus 25F. Once machined, the forging was nondestructively tested andpositioned for welding. Preheaters were installed inside thebore of the no :le, and thermocouples attached outside in the"3T" band of the groove. After preheating of the no::le to the,
required 300 F, it was allowed to " soak" for one hour prior toI , ~3 start of welding. Welding was performed per the instructions in

It was interesting to note that during the first six layersdeposited, no real prcblems were encountered. It was feared thatthe sidewalls of the groove could not be easily welded(especially using remote video). Because the torch wasmotori:cd, it could be easily positioned to have the arc impingeon the sidewall. Additionally, positioning of the filler wasalso easily done with it being motorized as well. These featuresare necessary for ease of operation in a high radiation field.With these featares, the six layers required by Code case N-432were deposited easily and the 60 groove shape was r.aintainedallowing conventional split weave beading to complete the joint.(See photos 5 thru 7, Appendix III).
During the welding of the groove, some difficulty was incurred onpasses 53 and 54 at the 90 location. The passes exhibited poorwatting into the side walls and heavy oxides were produced. Thelocation was ground and liquid penetrant examined. Noindications were found. As the spool of wire being used for
another filler spool was used for theI'_ filler was almost empty,'2xt passes without incident. Upon UT examination after groove:
(_lompletion, this location exhibited indications of non-fusion.This location was marked for further examination by sectioningand microscopic examination. This exam revealed inclusionsbetween beads and internally within the beads. This defect wascaused by an intermittent filler material quality problem. (Seeweld overlay for additional details and photos 25 and 26 AppendixIII).
Upon completion of welding, the no::le was post heated at 500 Ffor 2 hours minimum prior to cooling to ambient. After coolingto ambient for 48 hours * minimum, the groove weld was liquidpenetrant and ultrasonic inspected. With the exception of the UTindications at 90 , no defects were found.
Weld overlay
In order to do a wet / dry overlay, the nozzle was re-configured tohave a partial thermosleeve detail. (See No::le Mock-up DrawingAppendix II). With this configuration, one half (0 -90 -180 )would be filled with water (both stagnate and flowing at +40 F)and the other half (0 -270 -180 ) dry. This configuration wouldallow the welding to be affected by a severe (water backed)quench rate and a moderate quench rate (steel mass effect -
both conditions without the('_ increasing interpass temperature),'2nefits of preheat or post heat.\_/

The no::le assembly was instrumented with thermocouples at the 90and 270 center lines at the I.D. surface of the no::le bore.surface thermocouple was placed en the 45Additionally, an O.D.slope of the no::le and both the flowing water and stagnate waterwere monitored.

No HAZ cracking was observed in any cross-section, tensile, i4. or bend specimen despite hardnesses exceeding 425 Hv-10,
indicating a lack of sufficient hydrogen being absorbed ,
during the welding. The use of the GTAW process provides '
the lowest hydrogen levels of the commonly used process(SMAW, SAW, GMAW), plus the use of Inconel filler allows anyremaining hydrogen to be absorbed in the weld deposit ratherthan into the HAZ.

^TRUCTURAL OVERLAY QUALIFICATION TEST PROGRAM
1.0 Purpose of Test::
The purpose of this test program is to qualify a non-water-backed and water-| backed strue.tural overlay procedure which could be utilized in the reinforce-1
ment of ASME Section III, Class 1, reactor nozzles and safe-ends which have| in-service generated flaws in the weld joining the nozzle to the safe-end..
.
2.0 Objectives of Test _:il
| The cbjectives of this test program is to:i
f 1) Produce a procedure qualification meeting ASME Code Case N-432 toestablish base-line material properties.|
Produce a non-water-backed and water-backed overlay, which upon |-2) destructive testing, will yield similar material properties.|
| 3) Serve as a model for future qualifications.
Provide sufficient technical data to allow in-service repairs to| 4)' nozzle to safe-end welds by structurally reinforcing the affected
area by overlay welding with and without water in the affectedno::le/ safe-end.

6,0 Consideration o' Restraint:
Code Case d-432 and ASME Section III, NS-4321(c) require co.: siderationBoth The location of the groove weldof restraint in procedure qualification.meets C.C. N-432 requirements for self restraint by having sufficientmaterial thickness surrounding the cavity to be welded.
Code Cese N-432, para. 2.1(e) allows the assembly to qualify weld buildupprocedures provided the cavity is not less than the thickness of the weldAs most safe-ends are i to 1-3/16"buildup or 1 in whichever is greater.thick, and standard designed overlays are slightly less than wall thickness(for thru-wall cracks -360'), A 1" minimum depth groove shall be used.
As the overlay will be applied to a full scale mock-up containing actualmaterials and typical geometry, restraint that will be encountered onnozzles in service should be similar.To minimize any stiffening effects of the wet / dry interface divider plate,the plate shall be made from thin guage material which allows the nozzle(Seeand safe-end to band in cue to the expected weld shrinkage,,G
() Assembly Drawing).
7.0 Test Specimen Locations:
All destructive test specimens shall be as located on the test assemblyIt must be noted that test specimens may or may not comoly
with ASME Section III, NS-4334.2(a) due to the orientation of the groovedrawings.
For purposes of this test program,weld and overlay reinforcement weld.the test samples are taken at similar depths from the 0 D. surface of theforging and transverse to the axis of the welds.

as established by the nozzle forger using drop weight test is -30*F. Code Case N-432, the test temperature for Charpy "V"notch impact testing
shall be (RT NOT +60'F), +30*F.
9.0 Remote Sensing:
As most in-service nozzles and safe-ends are in high radiation fields whichrequire video remote controlled welding, all welding will be performed usingpulsed GTAW welding equipment with remote viewing of the arc and depositA Dimetrics Gold Track 11 welding

V Water Sacked:
Weter contained in arrulus space of the thermal sleeve and nozzle wall. Water wasconsidered to be stagnant with 20 feet of head pressure yet allowed to circulate(2 GPM maximum) at the welding heat input was absorbed by the water. Circulation| did not start until the water temperature had risen to approximately +60'f. Thewater temperature ranged from +41'T to 62*f peak with the majority of the weldingbeing performed with the water temperature in the range of +45'T to 65*f.

I WELD PP.OCEDURES PQR 745 AND 746 - Task No. 90-27
Two 2-1/8 in, thick weld coupons identified as WeldProcedures PQR 745 and 746 were sutrnitted to Lucius Pitkin, Inc.for Charpy impact testing and microhardness testing.
I(V) 508 Class 2 base metal containing a 1-1/8 in, deep Inconel 82 weldThe submitted coupons consisted of a 2-1/8 in. thick SA
deposit. Weld coupon PQR 745 had been welded with a 200 F preheatand no postheat. Weld coupon PQR 746 was welded using a 300 F
I preheat and a 500 F postheat, at I hr/in of thickness.
Standard 10 nm x 10 mm Charpy impact specimens were
Iprepared from the submitted weld coupons in accordance with ASMESection Il SA 370 and ASME Section Ill NS-2200. The orientation ofthe base metal and heat-affected ::one Charpy specimens are shown inFig. 1.
Five heat-affected cone and five base metal Charpy impactspecirmns f rcm each coupon were tested at +40 F. The highest and
I Icwest values for each set of five specimens was discarded and theaverage of the remaining three specimens calculated as given in
A Knoop microhardness survey was performed across theweld, heat-affected cone and base metal in 0.010 in. intervals.The results of the microhardness survey (converted to Rockwell) are
I given in Tables !! and III and Figs. 2 and 3.

|f~Introduction
I We received from the PSI-PTL Physical Testing Department one cross sectionof test specimen identified as PQR 395. According to memorandum from Mr. Neal
l_A. Chapman, dated April 5, 1990, we were requested to macroetch one entirecross section and characterize the relationship of the unaffected base metaland the fusion / dilution zones, the heat affected zones comparing grain sizesand the depth of tempering under the overlay and adjacent to the Inconel
I butter and to provide photos to support the characterization. We were nisorequested to run two sets of adjacent parallel traverses for bothmicrohardness test, as depicted in Exhibit 1. The microhardness traverseswere at Location A, B, C and D as shown in Exhibit 1.
Visual Examination
A mettilographic cross section though the veld plate coupon of PQR 395 isshown in Figure 1. The etchant used for SA 508 was 2% nital and for overlayand Stainless Steel base was HCL + H 02 2 + H O in 2:1:3 ratio. Figure 2 is the2macrograph showing the areas of interest on PQR 395, the etchant used was 2%nital.

A transverse section through the veld plate coupon was prepared for
1 metallographic examination. The micrograph of the base metal SA508 consistedof tempered martensite and some free ferrite as shown in Figure 3 and Figure 4at 100X and 500X respectively. The microstructure at the interface of overlay
Iand base metal S508 is fine grain tempered martensite as shovn in Figure 5 andTigure 6 at 100X and 500X respectively. There is some loss of carbon at theinterface (fusion line) Figure 7 shews the microstructure at the interf ace ofoverlay llAZ and the base metal, the tempered martensite in the llAZ is
I considerably finer then that of the tempered martensite of base metal $508.The microstructure adjacent to Inconel butter, midvall location at 500X isshown in Figure 8, there are regions immediately adjacent to the veldcontaining white etching ferrite grains, there is depletion of carbon. Movingaway from the veld metal, the llAZ consist of fine grtin tempered martensite asshown in Figure 9 and Figure 10 at 100X and 500X respectively.
Microhardness Evaluation
1 A Knoop microbardness inspection using a 500 gram load, was conducted atO the designated locations. The results are presented in Table 1 and Table 2O for the Knoop and Rockvell hardness respectively.
| aunta
The changes in the microstructure at the interface of the overlay andI buttered veld with the base metal SA508 is barely noticeable. At 200X, the
microstructure is very fine. At 500X, the microstructure appears to containwhite etching ferrite, evidently there is depletion of carbon. The grey
I phase, probably tempered martensite, is too inne to be resolved foridentification. An SEM examination at 2000X to 3000X or TEM analysis isnecessary for proper identification. The phases adjacent to white regionconsist of a mixture of original tempered martensite and retempered martensiteI as expected from a multi-pass velding operation.

RIPORT OT: Metallurgical Examination of Tvo TestSpecimens Identified As PQR 745 And 746
REPORT TO: PSI-PIL Physical Testing Depart Lent
REPORT POR: New York Power AuthorityI James A. Fitzpatrick Nuclear Power PlantPost Office Box 41Lycoming, in 13093
ATTENTION: Mr. Heal A. ChapmanWelding Engineer
O Introduction
We received from the PSI-PTL Physical Testing Department two cross sectionof tect specimens identified as PQR 745 and 746. According to memorandum fromMr. Neal A. Chapman, dated April 6, 1990, we were requested to macroetch oneentire cross section and determine and characterize the relationship of theunaffected base metal and the fusion zone, the heat affected zone comparinggrain sizes and depth of tempering under the veld and to provide photos toI support the characterization. We were also requested to provide two sets ofadjacent parallel traverses for the micro-hardness test. One traverse shallbe initiated in the base of the veld bead denoted " valley" and the other
I traverse initiating between veld beads denoted " peeks". The microhardnesstraverse location is shown in Exhibit 1.
I Visual Examination
A metallographic cross section through the veld plate coupon of PQR 745I and PQR 746 is shown in Figures 1 and 2 respectively. The etchant used for SA2 2 + H O in 2:1:3 ratio.508 was 2% nital and for the veld metal was HCL + H 0 2

A transverse section through the two veld plate coupons of PQR 745 and PQF* 746 vas prepared for metallographic examination. The micrographs of the base
metal 5508 are shown in Figure 3 and 4 at 100X and 500X for PQR 745 andh Pigures 4 and 5 at 100X and 500X for PQR 746. The microstructures in both theW cases are unhomogeneous, consisting of a mixture of parallel dark and white
bands. The dark band contains carbon rich tempered martensite and the Whiteband microstructure is also tempered martensite which has a greatar amount offerrite. Figures 7 and 8 are micrographe 6t interface of fusion line, at 100)and 500X of PQR 745, the location is at center of flat portion of weld.Tigures 9 and 10 are the corresponding microataphs of PQR 746. At the fusionline, microstructure for PQR 745 consist of fine white etchit.g grains offerrite depleted of tempered martensite. There is similar less of carbon forPQR 746 at the interface of fusion line. The microstructure at the edge of
h HAZ and base aetal is fine tempered martensite as shown in Figures 13 and 14m at 100X and 500X for PQR 745 respectively and the corresponding one in Pigure
15 and 16 for PQR 746,
tMicrehardness Evaluation
A Knoop microhardness inspection, using a 500 gram load was conducted atthe designated locations. The results are presented in Tables 3 and 4 for PQR745, Pnoop Hardness and Rockwell Hardness respectively and in Tables 5 and 6for PQR 746, Knoop Hardness and Rockwell Hardness respectively.
Results
The microstructure of the base metal SA 508 for PQR 745 and PQR 746was similar and exhibited a banded tempered martensite structure. The fintgrain microstructure at interface of fusion line of the veld and base metal SA ~
w 508 for both PQR 745 and PQR 746 at 500X revealed white etching ferritedispersed with a grey phase, however the pattern of the microstructure at the '
I interface was different. The grey phase was too fine to be resolved, prnbab'llit is tempered martensite. There was a loss of carbon for both PQR 745 and- yPQR 746 at the interface. 'I

Dear Dasid:
We have ectopleted your request of diffusible hydrogen values for your test identificationnumbers HY-150 and HY-300 in accordance w,th AWS A4.3-86. Enclosed are the datasheets frotn our tests. The results are:
Avera;;c Diffusible Hydrogen Standard Deviation of AserageTest Number (ml/100g) (ml/1COe)
''
HY-150 .6605 .3702HY-300 1.1005 .I117-
, I would recommend weighing the sample on your scales to compare the " weight after ~~
welding" to our values. Also, note inat the variation of HY-150 is much higher than that ofH Y-300.
Please call me if you have any questions or comments.
