[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The working principle of laser welding is to excite the laser-active medium in a specific way, such as a mixture of CO2 and other gases, YAG yttrium aluminum garnet crystal, etc., so that it oscillates back and forth in the resonant cavity to form a stimulated radiation beam. When the laser beam is focused and irradiated onto the surface of the workpiece, the workpiece absorbs the energy of the beam, and when the temperature reaches the melting point of the material, welding can be achieved.
