[0002] At present, the flaw detection of automobile stamping parts refers to a method of non-destructive testing of automobile stamping parts using detection technology. Flaw detection technology refers to the technical means of detecting materials or parts through detection equipment (such as ultrasonic probes, magnetic particle detectors, etc.) to obtain their internal defects, structure and performance information. In the automobile manufacturing industry, stamping parts are one of the most important parts, and their quality and performance directly affect the performance and safety of the entire vehicle. The flaw detection of automobile stamping parts can effectively detect the defects inside the stamping parts (such as cracks, inclusions, etc.) to ensure that the quality and performance of the stamping parts meet the relevant standards and requirements. At present, the commonly used automobile stamping parts flaw detection technologies mainly include ultrasonic flaw detection technology, magnetic particle flaw detection technology, eddy current flaw detection technology, etc. Among them, ultrasonic flaw detection technology is the most commonly used flaw detection technology, which can be applied to the flaw detection of various stamping parts. Ultrasonic flaw detection technology sends ultrasonic waves into the inside of the stamping parts, and determines the size, position and shape of the defects inside the stamping parts by receiving and analyzing the reflected ultrasonic signals.
