摘要： PURPOSE:To carry out precise automatic flaw detection by displaying reflected echoes due to an oblique angle ultrasonic wave and a small oblique angle vertical ultrasonic wave on the cathode ray tube of an ultrasonic flaw detector and setting the reflected echo from the small oblique angle vertical ultrasonic waves to the standard of a time axis to output and record only the reflected echo from the oblique angle ultrasonic wave. CONSTITUTION:The ultrasonic wave transmitted from a submerged small oblique angle vertical focusing probe 26 and impinging against a blade groove shoulder part 27 has a high propagation speed because it is a longitudinal wave in a rotor 1 to appear on a cathode ray tube as a blade groove shoulder surface echo K. The reflected echo due to the ultrasonic wave transmitted from a submerged oblique angle probe 16 to reach a blade groove corner part 6 in such a case that a creep damage flaw 7 or the blade striking flaw 13 in the vicinity of the corner part 16 is present appears on the cathode ray tube as a damage echo F or a striking flaw echo N. In this case, since the ultrasonic wave is a slow horizontal wave in the rotor 1, the reflected echo appears at a point separated from an echo S. Herein, since necessary data is only an echo F, only the creep damage flaw 7 can be detected.
