1. Select blanking and enter the next process after completion. Different stainless steel workpieces enter the corresponding process according to the processing requirements;

2. When bending, first determine the tool and groove used in bending according to the size on the drawing and the thickness of stainless 304 seamless steel pipe. Avoiding the deformation caused by the collision between the product and the tool is the key to the selection of the upper die (in the same product, different models of upper die may be used), and the selection of the lower die is determined according to the thickness of the plate.

3. In order to weld firmly, punch a bump on the workpiece to be welded, which can make the bump contact with the flat plate evenly before power on welding, so as to ensure the consistency of heating of each point. At the same time, it can also determine the welding position. It is necessary to weld. Adjust the preloading time, holding time, maintenance time and rest time to ensure that the workpiece can be spot welded firmly.
