Abstract

PURPOSE: To accurately estimate the size and property of a flaw, by making a wave receiving angle independently changeable regardless of the transmitting angle of an ultrasonic wave and measuring the mode kind and intensity distribution of the plate wave reflected from a flaw.
CONSTITUTION: A transmitter 11 and a receiver 12 are provided to an ultrasonic flaw detector and an ultrasonic wedge 15 is integrally provided to the transmitter. Pulse voltage is oscillated from a pulser 41 and an ultrasonic wave is transmitted to a material at an angle α from the transmitter 11. The ultrasonic wave 32 reflected from the flaw 22 of the material 21 s received by the receiver 12 to be sent to a receiving amplifier 2 and a display apparatus 43. At this time, the receiving angle θ of the receiver is changed to receive plate waves having different modes are received corresponding to respective angles θ. Because plate waves of all modes are measured by changing the receiving angle, a flaw reflected wave reflected in a mode different from that of transmitted plate waves can be detected and the size and property of the flaw can be accurately estimated.
