in the welding process of sheet metal numerical control stamping processing, the key is divided into three welding processing methods: two-piece t-seam welding, two-piece same-plane seam welding and two-piece l-seam welding. With different workpiece thickness, different welding methods, seam spacing is also changed. When the thickness of the workpiece that must be produced is 3 to 6mm, and the two pieces are welded on the same plan, double-sided welding is generally used with a spacing of zero to 2.5mm. Or the same workpiece thickness of 3 to 6 Mm, if two pieces of L-shaped butt-seam welding, double-sided welding is generally selected, and the seam interval is zero to 2 Mm.

the thickness of the workpiece that must be produced is one to three Mm, and two pieces of l-shaped butt seam welding is stipulated. generally, double-sided welding is selected, and the seam interval is zero to two Mm. Or the same workpiece thickness of one to three Mm, it is stipulated that two pieces of T-shaped seam welding, double-sided welding is mostly selected, and the seam interval is zero to two Mm. The thickness of the workpiece that must be produced is one to three Mm. It is stipulated that two pieces of the same plan are welded to each other. Usually, one side is welded with a seam interval of zero to 1.5 Mm.

Unless it is an integrally formed sheet metal part, in the production and processing of sheet metal parts, the workpiece cannot be separated from the welding and processing stages of sheet metal parts. Laser cutting manufacturers said that the sheet metal parts welding processing plant has the advantages of high structural compressive strength, good connector sealing, saving metal materials, and alleviating the total weight characteristics of the structure. There is also a lot of information to pay attention to during the welding process. For example, workpieces of different thicknesses must use different sizes of wave ports.

The laser cutting process shows that the fiber laser cutting cross section produces vertical texture, and the height of the line affects the surface roughness of the laser cutting appearance. The lighter the texture, the cleaner the laser cutting cross section. Surface roughness not only impairs the appearance of the boundary, but also impairs the friction characteristics. In most cases, the surface roughness must be reduced as much as possible. Therefore, the lighter the texture, the higher the laser cutting quality.
