When performing ultrasonic flaw detection, the dimensions of the vibrator 2 that emits ultrasonic waves are determined in consideration of the directivity of the ultrasonic beam. This is because if the dimensions of the vibrator 2 are too small, the spread of the ultrasonic beam becomes large and the flaw detection sensitivity deteriorates. Therefore, it is necessary to increase the dimensions of the vibrator 2 to some extent, and normally it is 5Mtlz, 10mm square, 2MHz 1
Requires a size of 20mm square. - On the other hand, the scanning interval needs to be small in order to perform precise ultrasonic flaw detection.
