Definition of laser welding

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 the heat conduction type, that is, laser radiation heats the surface of the workpiece, and the surface heat diffuses internally through heat transfer. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted, forming a specific molten pool. Due to its unique advantages, it has been successfully applied in precision welding of micro and small parts.
