[0002] Forging flaw detection refers to the process of non-destructive testing of forgings to detect defects and adverse conditions inside forgings. Common forging flaw detection methods include ultrasonic detection, magnetic particle detection, eddy current detection, etc. Ultrasonic detection uses the propagation characteristics of ultrasonic waves to detect defects inside forgings. By transmitting ultrasonic waves into the interior of the forging and observing the reflection and refraction of ultrasonic waves at the interfaces of different media, the location and size of defects inside the forging can be determined.

During the flaw detection process, it is not convenient for the probe to perform flaw detection according to the style of the curved surface. The probe needs to be adjusted and set, which is cumbersome. Therefore, the present application designs a surface flaw detection device for forging processing. Utility Model Content
