The crane machine non-destructive testing
time:Oct 19,2016
Non-destructive testing is that using the ray, ultrasonic waves, etc. to detect internal defects such as welds inside the steel and metal structures. The instrument can pass through the interior of the material, and based on certain principles, can sense the condition inside the steel material.
In general, the crane machine damage detection is common in the crane manufacturing process and is used to control the quality of machining and welding. Because when the crane machine is welded, it is limited by the welding process and the equipment, which will cause a certain deviation in the quality of the welding. This causes problems such as pores, slag inclusions, and cracks in the welded welds to a certain extent and in different numbers. These defects affect the stiffness, toughness, etc. of the crane machine metal structure and reduce the performance of the crane machine.
In order to reduce and eliminate the defects of castings, parts and welding processes, ensure the safety performance of the crane machine, can adopt the non-destructive testinghe to detect, position and quantify to improve the quality of the crane machine.
