ABSTRACT:
A two-probe ultrasonic flaw detection apparatus, in which an ultrasonic wave is transmitted from a transmission probe into an object being inspected and ultrasonic waves reflected from a reflection surface in the object are received by a reception probe, operates to determine the position at which the combined intensity of ultrasonic waves reflected from each part of the reflection surface form a maximum. The reception probe is then moved to the position of maximum reception intensity. The position of maximum reception intensity is determined using as input parameters the ultrasonic characteristics of the object being inspected and of the transmission and reception probes, and the position of the transmission probe and the angle of incidence of the ultrasonic wave into the object.
