Abstract: Ultrasonic flaw detection uses a phased-array ultrasonic-flaw-detection probe. The flaw detection probe is placed such that the center of curvature of the flaw detection probe coincides with a reference center of curvature of a subject. The flaw detection probe is translated along a scan direction. The flaw detection probe emits an ultrasonic beam such that the position upon which the ultrasonic beam converges coincides with the center of curvature of the curve of the outline of the cross section of the subject at the scan position, receives the resulting reflected beam, and estimates the length of a flaw in the circumferential direction of the subject. In addition, the estimated length of the flaw is corrected using a correction coefficient corresponding to the distance between the center of curvature of the reference scan position and the center of curvature of the scan position in the thickness direction of the subject.
