    Surface-breaking crack in a 50 mm thick weld, undetected by radiography

    Combining Different Techniques for Full-Weld Coverage and Improved Efficiency

    PHASED ARRAY PULSE-ECHO TECHNIQUEThe phased array technique uses a mosaic of transducer ele-ments in which the timing of the elements excitation can be individually controlled to produce a certain desired effect, such as steering the beam axis or focusing the beam.

    PULSE-ECHO TECHNIQUEThe pulse echo technique is an ultrasonic test in which dis-continuities are detected by the reflected echoes from defects.

    TIME-OF-FLIGHT DIFFRACTION (TOFD) TECHNIQUEThe time-of-flight diffraction technique is an ultrasonic test that relies on the diffraction of ultrasonic beams from the corners and ends of internal structures (primarily defects) in a component being tested.

    CREEPING WAVE TECHNIQUEThe creeping wave technique is an ultrasonic test in which discontinuities are detected by the return of a creeping wave that tracks the surface of the component being tested.

    Ultrasonic Weld Inspection SolutionsOlympus has created the AUT PV solutions (automated ultrasonic testing) to provide you with an affordable means to inspect welds according to code. These solutions are portable and can be put to work virtually anywhere. The perfect combination of acquisition unit, scanner, encoder, and software makes the inspection of pressure vessel welds and other welds an easy task.

    Fast inspection of small- and large-diameter welds 100% volumetric weld coverage Adaptable to butt welds, circumferential welds,

    long seams, one-sided access configuration, and most common weld profiles

    Inspection of wall thicknesses from 8mm to 300mm and part diameters from 100m to flat

    Digital archiving of inspection data Elimination of film archiving Portable for in-house and field inspections Improved productivity compared to radiography Improved probability of detection (POD) compared

    to radiography

    Analysis of the weld inspection results given by AUT and radiography shows that AUT provides both depth and height information, and is more sensitive to planar-type defects while eliminating radiation hazards.

    Automated Ultrasonic Testing Versus Radiography TestingUltrasonic technology has been proven very effective for pressure vessel weld inspections and it is easily adapted to common codes such as API and ASME Sec III, V, VIII, CC2235, CC2599, and CC2600.

    OmniScan UT 8 channel UT flaw detector

    Closed umbilical cable

    Pulse-echo channel, 60 shear wave for weld cap coverage.

    Pulse-echo channel, 70 shear wave for weld root coverage.

    TOFD channel for weld volume coverage.

    Combining pulse-echo and TOFD channels offers complete coverage of the weld.

    PV-100Pulse-Echo and TOFD Inspection SolutionThe PV-100 solution is based on the proven OmniScan UT flaw detector. This advanced UT instrument uses two inspection techniques simultaneously. The combination of time-of-flight dif-fraction (TOFD) and the pulse-echo or creeping wave technique allows a full volumetric inspection in a single pass. Inspection results are available instantaneously providing immedi-ate code based acceptance or rejection. This solution was specifi-cally designed to meet the productivity requirements of construc-tion welding in petrochemical and power-generation industries.

    Amongst other advanced tools, TomoView analysis software offers a TOFD Man-ager for calibrations, lateral wave straightening, lateral wave removal, and synthetic aperture focusing technique (SAFT). In addition a C-scan Merge tool merges interleaved C-scans based on minimum or maximum amplitude, or TOF.

    PV-200Phased Array and TOFD Inspection SolutionOlympus has developed a versatile phased array solution for weld inspections. The PV-200 solution uses a variety of techniques to achieve a productive and efficient inspection. Phased array tech-nology allows the scanner to adapt to different weld inspections without changing the probe position. This dramatically reduces setup time and eliminates many of the mechanical components needed with conventional ultrasonic probes. Fewer mechanical parts means fewer mechanical failures.

    Fast setup without manual probe adjustment Easy adjustment of ultrasonic parameters Smaller, more versatile scanners easily adjust to different weld

    configurations. Complete weld coverage in a single passThe PV-200 solution brings together an Olympus acquisition unit, scanner, probes, and software tailored to your needs. The acquisition unit controls all the multielement-probe channels. The software is equipped with a dedicated calculator that guides you when changing beam angles, depth, and focus without moving the probe. Length and depth sizing for code acceptance /rejection is performed at the time of the inspection and results are recorded rapidly.

    PV-200 ATTRIBUTES Inspect immediately after welding to help you monitor the

    welding process. Detect and size vertical defects using TOFD and tandem

    techniques (requires instrument with P-R option). Maximize the probability of detection (POD) with controlled

    focusing. Create an automatic setup procedure for any weld profile. Reduce data analysis and reporting time. Many inspection parameters such as weld profile are

    accommodated in software offering improved flexibility.
