Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding mechanism for workpiece processing. Background Art

[0002] The laser welding mechanism uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material and fixing it. In the process of processing some workpieces, such as round tubes, it is necessary to use a laser welding mechanism to process metal seals to seal and weld metal round tubes.
