The stainless steel angle bar must be carried out in accordance with the standard during the welding process, in order to minimize the problem of the stainless steel angle bar in the welding process. 　　

1. Use a smaller welding line energy, the welding line energy is proportional to the size of the current, and inversely with the welding speed. 　　

2. If there is only one welding seam on one side, the back welding is adopted from the middle section. 　　

3. If there are two or four symmetrical welds, start welding from one end, and use the symmetrical cross-welding method. 　

The stainless steel angle bar is welded in accordance with the standard, which can reduce the deformation of the steel to a greater extent. This is the professional standard specification.
