Description

Ultrasonic testing is difficult for cast stainless steel which is used as the material of main coolant pipes in pressurized water reactors, because of the large attenuation and scattering of ultrasonic waves caused by its macro structure. Ultrasonic testing for the axial fatigue crack on welding area in the test piece of the cast stainless pipe was performed, using the double large aperture ultrasonic probes. In this study, depth sizing of defects was performed under the positive result of the detection of defects in former study. As a result, sizing of defects with over 20mm target depth for the specimen thickness 69mm is highly possible. (author)
