Description

Technical Field

[0001] The utility model belongs to the technical field of welding machines, and in particular relates to a handheld air-cooled laser welding machine. Background Art

[0002] The laser welding machine 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 to form a specific molten pool.

[0003] In traditional handheld air-cooled laser welding machines, the welding host and the wire feeder are separated. When in use, the welding host and the wire feeder need to be carried separately. The welding wire is extended through the wire feeding tube for welding. When the wire feeding tube is extended from the wire feeding machine, it is easy to bend due to the collision with the wire feeding machine wall and human swing, which causes the welding wire to bend or even be blocked and cannot be smoothly extended from the wire feeding tube, affecting the welding effect.

[0004] Among the existing patented welding machines with integrated wire feeders, the patent announcement number is CN219169852U, and the patent name is gas shielded welding machine for large workpieces. It discloses a workbench, a welding wire barrel is placed on the inside of the workbench, a wire feeder is placed on the top of the platform, a dust cover is arranged on the top of the welding wire barrel, one end of the welding wire casing is connected to the dust cover on the top of the welding wire barrel, and the other end of the welding wire casing is connected to the wire feeding mechanism of the wire feeder. Although the wire feeder is integrated, the wire feeder is located on the outside of the device, and its wire feeding tube is still placed in the outside world and is easily affected by the external environment, resulting in unstable welding wire output; the existing welding machine with built-in wire feeder needs to place the wire feeder and components such as optoelectronics in the same closed space, which is likely to cause safety hazards, affect the service life of the welding machine, and also cause danger to the staff.
