NOTICE:
Someone recently asked why some steel structure parts of the raw material of the rock mucking loader are to be subjected to stress relief after welding. Today we will talk about it.
After welding some steel structure parts of the tunnel mucking machine, there is no obvious welding deformation due to its good rigidity, but the welding stress is quite large. After using the tunnel mucking machine for a period of time, the steel structure may be released for some reason. It came out and caused deformation, so that it was destroyed, affecting the use of rock loading machine.
Therefore, for some important steel structures, such as rock mucking loader, high-pressure container, dangerous medium container, boiler, etc., various methods are used for stress relief after welding, the purpose is to prevent the internal stress in the steel structure from Hazard.
