How the ultrasonic flaw detector works

How the ultrasonic flaw detector works

When the ultrasonic wave propagates in the material to be tested, the acoustic properties of the material and the change of the internal structure have a certain influence on the propagation of the ultrasonic wave. The technique of understanding the material properties and structural changes by detecting the degree and condition of the ultrasonic wave is called ultrasonic testing. Ultrasonic testing methods generally include a penetrating method, a pulse reflecting method, a tandem method, and the like.

Digital ultrasonic flaw detectors usually send ultrasound to the object to be measured (such as industrial materials, human body), and then use its reflection, Doppler effect, transmission, etc. to obtain information inside the object under test and process it to form an image.
