Excellent Possible Option

The Lincoln Solution

Invertec® 135-S

For welding these (stainless) covered electrodes, Lincoln Electricoffers a complete range of welding equipment: both inverters andconventional rectifiers.

Inverters use modern light weight technology; this allows for portable machines with excellent welding characteristics. Withinthe range, the maximum output current varies from approx. 120A(135-S) to 400A (400-SX).

The Lincoln Electric range is completed with the conventional rectifiers LINC 405-S/SA and LINC 635-S/SA with respectively400A and 670A output.

All machines have3 Arc Force: temporary increase of output current when the

arc is too short, to prevent the electrode from sticking duringwelding

3 Hot Start: temporary increase of the output current during thestart of a weld to help ignite the arc quickly and reliably.

Depending on the type, these features are either pre-set ormanually adjustble.

Arc Force Control

All machines have input voltage compensation, and so can be powered from motor generators for site applications. The smaller machineshave 230V, single phase input, the heavier machines have 3 phase input. The Inverters are lightweight, all power sources are built the‘Lincoln Way’: Rugged and Reliable.

For the most common applications involving 304L, 316L, their stabilized equivalents AISI 347 (X6CrNiNb 18-10, M.Nr. 1.4550), 321 (X6CrNiTi18-10, M.Nr. 1.4541), 316Ti (X6CrNiMoTi 17-12-2, M.Nr. 1.4571) and 318 (X6CrNiMoNb 17-12-2, M.Nr. 1.4580), and combinations of these stainless steel types with CMn steel (including claddings) the preferred Lincoln Electric covered electrodes are given in the table above.

Packaging solutionsPackaging plays a very important role during the transferof the stick electrodes from the manufacturing place tothe application location. Its role is multiple as it has to :

1. Protect stick electrodes against potential damageoccurring during transportation and storage.

2. Prevent interactions between moisture from thecoating and moisture from the atmosphere.

3. Identify the electrodes.Because the stainless steel stickelectrode application range is broad and because eachapplication requires its own degree of weld quality andquality assurance, Lincoln extends its stainless steel stickelectrodes packaging offer to better respond to differentcustomer needs.

The Linc CanTM provides an optimum compromisebetween the cost effective cardboard and premiumSahara ReadyPack® packaging options.

• Cardboad for regularapplications without specialrequirements.

• Linc CanTM for severe workingconditions and when a guaranteeon moisture absorption resistanceis needed.

• Sahara ReadyPack® for the mostdemanding applications, such asduplex and super duplex thatrequire an absolute guarantee forlow diffusible hydrogen and/or lowmoisture level.

Stainless steel Electrode customer requirements Microstructure

The success of a stainless steel covered electrode is determined by the appreciationof both welders and welding engineers/management. Both groups have differentrequirements: welders want a user friendly electrode that does the job; weldingengineers and the management want an economic solution for the qualityrequirements they have to fulfil. The most important requirements are:

The welder3 Electrode easy to bend slightly, without cracking of the coating3 Easy striking, no sticking electrodes / extinguishing arc3 Stable arc that is easy to direct 3 No spatter3 Good side wall wetting, no undercut3 Good slag detachability, no shooting slag3 Pore free weld metal3 A user friendly electrode that does the job

The welding engineer/management3 Economy: long (350/450 mm) electrodes, short stub ends 3 Approvals3 Moisture resistant electrode coating3 Matching core wire: no local compositional variances3 Composition fulfilling as much classification societies as possible (e.g. > 2.7% Mo

for 316L types of weld metal)3 Balanced ferrite content to prevent hot cracking, local corrosion (and s-phase after

PWHT)3 High quality products that provide an economic solution

The Limarosta® and Arosta® range of general purpose stainless steel electrodes havebeen designed to meet all requirements of both the welders and the weldingengineers/management. Of course, both ranges have specific features that makethem the optimum choice for different applications:

Prediction of microstructure of stainless steel weld metalIn the Schaeffler/De Long diagram, the position of the undiluted weld metal of different products is shown. This diagram can be usedto predict whether or not welding of dissimilar metals can cause problem regarding composition or microstructure (e.g. hot cracks due to too low ferrite, brittle weld due to martensite)

The basic advantage of stainless steel is that it can be applied in a corrosive environment due to the formation of a thin protective layer of Chromium oxidethat is formed on the surface of steels containing more than 12% Cr. The mainapplication of stainless steels is to withstand aqueous corrosive solutions.Furthermore, specific stainless steels have been developed to withstand hightemperatures (oxidation), high stresses at high temperatures (creep) and extremelow temperatures (cryogenic applications).

The most common stainless steels contain 17 - 18% Cr, 8 - 13% Ni, 0 - 5% Mo (3XX AISI range). These materialshave an austenitic structure that makes the material tough and ductile. They are considered to have goodweldability.

The basic austenitic stainless steel is AISI 304L (EN 10088-1 X2CrNi 19-11, Material Nr. 1.4306). This materialgives protection to general corrosion. When chlorine ions are present in the corrosive environment, AISI 304L isnot resistant to the special type of corrosion that occurs: Pitting. AISI 316L (EN 10088-1 X2CrNiMo 17-12-2, M.Nr.1.4404), which contains 2 - 2.5% of molybdenum, is more resistant to this type of corrosion. Based on these twogrades, a whole range of different compositions has been developed with specific properties.

Besides the austenitic 3XX stainless steels, there are ferritic, martensitic, ferritic-austenitic (duplex) and fullyaustenitic stainless steels which all have their own specific advantages. Lincoln Electric Europe has outstandingconsumables for each of these special stainless steel ranges and for nickel base alloys. Although they are notfurther discussed in this document, your local Lincoln representative or distributor can provide you with moreinformation or transfer your questions to the product specialists of Lincoln Electric Europe.

CorrosionThe type of corrosion that may occur depends on the composition of the applied steel grade, the corrosive mediumand process temperature. Whether a metal (base material or weld metal) can withstand corrosion is in principledetermined by its chemical composition. However, imperfections in the construction (crevices, local oxidation orremaining slag due to welding) can affect the corrosion properties of a material

General corrosionUniform decrease of material thickness.

Pitting corrosionThe material shows small (local) pits, that may deepen rapidly. Locally theprotective passive oxide layer of the material has disappeared.

Crevice corrosionThis form of corrosion occurs in crevices: locations where no oxygen canpenetrate in the liquid. There is no oxygen to form the passive protectivelayer, thus giving corrosion.

Contact or galvanic corrosionWhen a “noble” material is combined with a “less-noble” material in aconductive liquid, the less-noble material will corrode. Prevent small “less-noble” parts in a large “noble” construction.

Stress corrosionStresses combined with e.g. hot solutions containing chlorine or sulphideions can cause stress corrosion cracking. Ferritic-austenitic (duplex)stainless steels are used for this application.

Intercrystalline corrosion3XX with more than 0.03 %C may suffer from the formation of chromiumcarbides and hence Cr depletion in the HAZ, givingintercrystalline corrosion. 3XXL or Nb/Ti-stabilised types prevent thisphenomenon.

Technology featuresPorosity, caused by coating moisture is nolonger an issue: Lincoln Electric Europe haseliminated this problem by developing acoating that limits moisture absorption.

This prevents porosity in general, but alsothe well-known starting porosity. Welders nolonger have to overcome starting porosity byshort-circuiting the electrode; this had therisk of loosing a part of the electrode coatingwhen breaking the short circuit.

EconomyThe most economic welds areachie-ved by:

3 Welders that appreciate theelectrode they use. (They will show ahigher productivity.)

3 Long electrodes (350/450 mm) withshort stub ends: reduce the amountyou throw away, and increase theduty cycle

3 High quality products with balancedchemical analysis and microstruc-ture
