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 belongs to heat conduction type, that is, laser radiation heats the surface of the workpiece, and the surface heat diffuses internally through heat transfer. By controlling the parameters such as laser pulse width, energy, peak power and repetition frequency, the workpiece melts and forms a specific molten pool. Because of its unique advantages, it has been successfully applied to the precision welding of micro and small parts. The emergence of high-power CO2 and high-power YAG lasers has opened up a new field of laser welding. Deep penetration welding based on keyhole effect has been widely used in machinery, automobile, steel and other industrial fields.
