Description

The basic principle of ultrasonic testing is: Using the reflection and refraction of ultrasonic wave at the interface (the joint surface of two media with different acoustic impedance) and the attenuation of ultrasonic wave propagating in the medium, the transmitting probe transmits ultrasonic wave to the inspected part, and the receiving probe receives the ultrasonic wave reflected back from the interface (defect or background) or the transmitted wave after passing through the inspected part (transmission method). In this way, the spare parts are detected whether there are defects, and the defects are located, qualitative and quantitative.
