[0002] At present, there are many different flaw detection devices on the market. The types of these flaw detection devices include radiographic flaw detection, magnetic particle flaw detection, ultrasonic flaw detection, infrared flaw detection, etc. Each of these flaw detection devices has advantages and disadvantages. For example, the most commonly used radiographic flaw detection device has the widest applicability and It is not limited by the material, but the radiographic inspection equipment is expensive, and it is necessary to add a shielding cover during the week of radiographic inspection to reduce the damage of the radiation to the staff, and the cost of later equipment maintenance is high

[0003] The principle of magnetic particle flaw detection is not complicated. The surface of the flaw detection piece is covered with magnetic powder. Because the defects inside the material will affect the distribution and direction of its own magnetic domains, the distribution of magnetic particles will be different; however, damage identification requires experienced workers. Judging by naked eyes, the effect of automatic flaw detection cannot be achieved. Secondly, magnetic particle flaw detection is suitable for ferromagnetic components, which has a large range limit. Magnetic particle flaw detection can only show the position of the defect of the flaw detection part, and cannot judge the depth of damage. Substantial basis

[0004] Ultrasonic flaw detection is suitable for materials with smooth and flat surfaces. Its structure is simple and easy to operate; while infrared flaw detection is mostly used for the detection of electronic components. It can easily find abnormal temperature rise caused by short circuit when electrical components are running; The flaw detection of building materials has to rely on expensive radiographic flaw detection or magnetic particle flaw detection, which cannot save equipment costs and reduce the labor intensity of workers
