In the process of steel structure processing, there are often deformation problems due to welding. The causes of deformation of steel members are hot deformation, cold deformation or the mutual components can not be assembled together. The deformation problem is very difficult to solve in the process of steel structure processing. For example, the assembly process of steel structure cannot be smoothly assembled, and the welding deformation will occur in the welding process of steel structure.The required tolerance is too large.Hebei 3D steel structure [stock code 832621] has nearly 20 years of steel structure manufacturing experience, and has rich experience in correcting steel structure deformation. The deformation often occurs in the process of steel structure processing, which is caused by welding hot deformation. So how to correct the steel structure processing deformation.

Case study of 3D steel structure processing 1

     1、 The fixture fixation method of steel structure processing usually uses the fixture with great rigidity to clamp the assembled weldment, and then weld it. When the steel structure member encounters thermal deformation, it needs to use the clamp force to correct, so as to control the steel structure processing deformation.

     2、 In the process of steel structure processing, the reverse deformation method is used. Before welding, the component is judged according to the condition of the metal component to be welded. If it is cooled after welding, the direction deformation and shrinkage will decrease.It can be bent or tilted in the opposite direction in advance. The welding will deform when it is heated and can be restored to the predetermined position.

     3、 Steel structure processing positioning control method, steel structure parts before welding, using many welding points to locate the welding position or around, can also press heavy objects on both sides of the weld, this method is called positioning control method.

     4、 Steel structure processing and welding sequence method, correctly arranging the welding sequence of steel structure processing, can effectively prevent steel structure welding deformation. Generally, the deformation caused by the first welding seam is very large, and the deformation amount caused by each welding seam can not offset each other. The deformation direction of the later welding seam is the same as that caused by the first welding seam.
