Ultrasonic flaw detector apparatus and ultrasonic flaw-detection method

An ultrasonic transceiver has a function of displaying a modified B scope. The ultrasonic transceiver transmits ultrasonics to an inner part of a test object at an angle of inclination to a surface of the test object, receives echoes from discontinuity in the test object, and displays, based on an outcome of the reception, an image which shows a state of transmission of the ultrasonics in the test object. When displaying the image, origins of time axes on the screen are shifted through a coordinate transformation of the outcome of reception to avoid the difference in lateral positions of images of single discontinuity. Consequently, it is possible to accurately discern the location, size, configuration, and posture of the discontinuity when the outcome of reception is displayed in a rectangular display window.
