Non-destructive testing use radiation, ultrasonic, etc., to inspect the machine and metal structures steel weld defects. According to certain principles, The instrument can pass through the material interior to sense the steel material interior. In general, Industrial Gantry Crane damage detection is common in the crane manufacturing process, used to control the processing, welding quality. Because during the Industrial Gantry Crane welding, limited by the welding process and the on-site equipment, the quality of welding will be deviated by a certain degree, resulting in different degrees and different numbers of pores, slag inclusions and cracks in the welds. These defects will affect the rigidity and toughness of the industrial gantry crane metal structure, reducing the crane's performance.
Reduce, eliminate castings, spare parts and welding process defects, can improve industrial gantry crane safety performance, using non-destructive testing defect detection, positioning, quantitative, so as to improve the crane quantity.
