[0002] Laser welding is a welding method that uses a focused laser beam as an energy source to generate heat to bombard the weldment. Due to the optical properties of lasers such as refraction and focusing, laser welding is very suitable for welding micro parts and parts with poor accessibility. Laser welding also has the characteristics of low heat input, small welding deformation, and is not affected by electromagnetic fields.
