摘要： An ultrasonic probe performs flaw detection of a high (t/D) metal pipe. The front end portion of a transducer has at least a portion with an asymmetrically curved shape having a radius of curvature which progressively increases from one end towards the other end of the front end portion. The probe is disposed with respect to the pipe with its end having the smaller radius of curvature positioned on the side away from the direction of propagation of refracted waves, the end having a larger radius of curvature thereof positioned on the side in the direction of propagation of refracted waves. Angle beam flaw detection is carried out such that incident waves are generated which generate refracted longitudinal waves which do not reach the inner surface of the metal pipe and refracted transverse waves which are focused on the inner surface of the pipe.
