Solution: Causes of deformation of steel grating
Dec 09,2024
There are many reasons for the deformation of the steel grid, such as large size, insufficient thickness of the material, hot-dip galvanizing during surface treatment, etc. In the welding process, if affected by some high temperature heat source, the weld area will be rapidly heated and partially melted, resulting in thermal expansion of the material, while the relatively low temperature area around the welding area will be bound, resulting in elastic thermal stress, resulting in thermal compression and uneven shortening deformation. In addition, the severe impact of external forces during loading and unloading will also cause deformation of the steel grid.
In order to avoid the deformation of the steel grating, the input heat source energy can be reasonably controlled during the manufacturing process, which is of great significance to the quality of the steel grating weldment. In addition, during the surface treatment process, care should be taken to avoid high temperature to avoid deformation. For the deformed steel grating, some simple and easy-to-operate methods can be used to correct it, but it must be noted that the intensity is not too large, otherwise it will be counterproductive. If the deformation is serious, can only re-production
