[0002] Nondestructive testing is a general term for all technical means that utilize the characteristics of sound, light, magnetism and electricity to detect whether there are defects or unevenness in the inspected object without damaging or affecting the performance of the inspected object, and to provide information such as the size, location, nature and quantity of the defects, and then determine the technical status of the inspected object (such as whether it is qualified or not, service life, etc.). When using existing nondestructive testing, there is a method of manually moving the nondestructive testing probe to test the product. This method has high labor intensity, low detection efficiency, and is prone to reduce the problem of detection quality. Utility Model Content
