Description

technical field [0001] The invention relates to a laser wire-filling processing device and a wire-filling method. The invention relates to a device and method for laser wire-filling welding, repair and additive manufacturing under vacuum conditions, belonging to the category of vacuum laser processing. Background technique [0002] Laser welding is widely used in many industrial fields such as aviation, aerospace, petroleum and chemical industry due to its advantages of high power density, fast welding and cooling speed, small heat-affected zone and easy automation. Due to the rapid development of industrial lasers in recent years, high-power and high-quality lasers are widely used in the field of laser welding. In order to avoid the interference of plasma on the welding process during high-power laser welding and improve the quality of laser welding, vacuum laser welding technology has emerged in recent years. Vacuum laser welding combines the dual advantages of laser weld...
