Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, specifically a handheld laser welding machine with an integrated wire-filling mechanism. Background Technology

[0002] A handheld laser welding machine is a high-efficiency welding device based on laser technology. It primarily relies on a high-energy-density laser beam to locally heat the workpiece surface, melting the metal and forming a weld joint. During operation, the laser generator emits a highly monochromatic and directional laser beam, which is transmitted to the welding head via optical fiber. The operator holds the welding head and aligns the laser beam with the workpiece surface to be welded. After focusing, the energy is highly concentrated within a small area, instantly heating the metal to a molten state. Subsequently, the molten metal re-solidifies under surface tension, forming a stable weld joint.

[0003] Chinese Patent Publication No. CN117961201A, authorized on May 3, 2024, describes a laser welding machine with an integrated wire feeding mechanism. This not only solves the problem that current handheld laser welding machines on the market only function as a light source and require a separate wire feeder to deliver the welding wire, but also has good heat dissipation capabilities.
