Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type, that is, laser radiation heating workpiece surface, surface heat through the heat conduction to the internal diffusion, through the control of laser pulse width, energy, peak power, and repetition frequency, and other parameters, so that the workpiece melting, the formation of a specific molten pool.
