Abstract

PURPOSE: To perform ultrasonic flaw detection of defective parts satisfactorily irrespective of the variations in the thickness of the material to be examined by comparing the time until the reflected waves from bottom face and defective part are received based on the time when the surface reflecting waves of the material to be examined are received at the ultrasonic flaw detection.
