[0003] 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, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully used in the precision welding of micro and small parts.
