Background
Ultrasonic flaw detectors generally use an ultrasonic probe to make good contact with the surface of a workpiece to be detected, and the probe can effectively transmit ultrasonic waves to the workpiece, receive the ultrasonic waves reflected by an interface, convert the ultrasonic waves into electric signals and transmit the electric signals to an instrument for processing. The position of the defect can be known according to the propagation speed and propagation time of the ultrasonic wave in the medium. The larger the defect, the larger the reflection surface, and the larger the reflected energy, so that the size of each defect can be found from the size of the reflected energy.
