Reasons for deformation of stainless steel plate

Laser welding of stainless steel plates mainly refers to the welding method that uses laser energy as a heat source to melt and connect workpieces. In the laser process, fusion occurs, and laser irradiation produces a stainless steel plate effect. The cost of fusion is reflected on the surface of the material, with some being absorbed and entering the material to complete the fusion target. In short, the process of laser welding involves using a high-power laser beam focused by an optical system to irradiate the surface of the material to be welded. Then, the material is fully utilized to absorb light energy, heat, etc. for processing the 304 stainless steel plate, and then frozen during the melting and welding process to form a welded joint.

The main factors affecting the deformation of stainless steel plate welding are welding current, long pulse width and frequency, increase in welding current, increase in weld width, and gradual appearance of spatter. These factors lead to oxidation changes and roughness of the stainless steel plate shape on the weld surface 201. The overall heat transfer coefficient of a metal depends not only on its thermal conductivity, but also on other factors.
