Steel structure processing process often encountered due to welding deformation problems, the cause of steel component deformation is thermal deformation, cold deformation or due to mutual components can not be assembled in one, deformation problem is the most difficult to solve in the process of steel structure processing, such as steel structure parts assembly process can not be smoothly assembled, steel structure welding process will appear welding deformation, technical requirements tolerance is too large. Deformation is often encountered in the process of steel structure processing, which is caused by welding heat deformation, so how to correct the steel structure processing deformation problem.

First, steel structure processing fixture

fixing method, usually use a very rigid fixture to clamp the combined weldment, with forced force to control the deformation problem, and then weld, when the steel structure encounters thermal deformation, it is necessary to use the fixture force to correct, to achieve the control of steel structure processing deformation problem.

Second, the reverse deformation

method in the steel structure processing process, before the component is welded, according to the situation of the welded metal component, such as cooling after welding, the direction deformation and shrinkage will decrease. It can be bent or obliquely in the opposite direction in advance, and the welding will be deformed after heat and can be restored to the predetermined position.

Third, steel structure processing positioning control method,

steel structure parts before welding, with many welding joints to locate the welding part or around, can also press heavy objects on both sides of the weld, this method is called positioning control method.

Fourth, steel structure processing welding sequence method, correct arrangement of steel structure processing welding sequence, can effectively prevent steel structure welding deformation, usually the first weld caused by the largest deformation, each weld caused by the

amount of deformation can not cancel each other, the final deformation direction, and the first weld caused by the deformation direction is consistent.
