Do You Know How The Ultrasonic Flaw Detector Works?

Ultrasonic flaw detectors mainly uses the propagation characteristics of ultrasonic waves in the workpiece, such as the loss of energy when the sound waves pass through the material.

Subtraction, reflection, etc. occur when encountering two media interfaces with different acoustic impedances. Ultrasonic flaw detectors working principle is:

1. The sound source generates ultrasonic waves, and the ultrasonic waves enter the workpiece in a certain way.

2. Ultrasonic propagation in the workpiece encounters different media interfaces (including the interface of defects in the workpiece material), making it pass

The broadcast direction or feature changes.

3. The changed ultrasonic wave is received by the detecting device, processed and analyzed, and the workpiece itself and its interior are evaluated.

Whether there are defects and defects.
