概要

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 ultrasonic scattering by the huge grain of the material. Therefore we performed ultrasonic testing for the axial fatigue crack on welding area in the test piece of the cast stainless pipe, using the double big-size ultrasonic probes which we developed. And we simulated the ultrasonic beam behavior using finite element ultrasonic propagation simulation code to optimize the test conditions.
