The principle of ultrasonic flaw detection is that when ultrasonic waves propagate through the material being inspected, the acoustic properties and internal structure changes of the material have a certain impact on the propagation of the ultrasonic waves. By detecting the degree and condition of the impact on the ultrasonic waves, we can understand the material's properties and structural changes.
Ultrasonic flaw detection is divided into manual and automatic methods, and we adopt the automatic method.
