Sheet metal welding is a process commonly used in sheet metal processing to join parts together as required. However, in the actual production process, if not done properly, it will lead to deformation of the workpiece. The following are the precautions to be taken for welding：
(1) Choose the proper welding sequence. For welded structures with more components, the components should be welded separately and then assembled and welded as a whole after correction. In this way, it is better than assembling into a whole first and then welding, which has a smaller chance of welding deformation, and the local places can be welded while assembling and the operation is more convenient.
(2) Select a reasonable welding sequence. In order to prevent welding deformation, in the welding sequence, should take the strip welding method, back welding method and symmetric welding method.
(3) anti-deformation method. Is to give the welded parts before welding a deformation and welding deformation in the opposite direction, after welding just to offset the deformation of the workpiece before welding.
(4) rigid fixation method. This method is very effective in reducing welding deformation.
(5) the choice of reasonable welding methods and specifications. Various welding methods to heat the weld energy density and heat input is different, for thin plate welding, the use of high energy density welding methods, such as the use of carbon dioxide gas shielded welding, plasma arc welding instead of gas welding and manual arc welding, it can reduce welding deformation. When welding aluminum and aluminum alloy structure, gas welding than manual argon arc welding deformation is much larger.
