Features of vacuum laser welding
1. Adapt to the welding of various metal materials, carbon steel, stainless steel, high strength steel, aluminum, copper and alloy materials.
2. Can be continuous or pulse out of the light, not only can realize the heat conduction welding, but also can be continuous deep fusion welding. It can realize spot welding, butt welding, stack welding, sealing welding, seam welding and so on.
3. Adopting continuous fiber laser, beam quality, maintenance-free, pump source service life is more than 100,000 hours.
4. Small thermal deformation and heat-affected zone (suitable for processing high melting point, high hardness, special materials).
5. Complex shapes of parts, tiny pieces can be processed, but also in a vacuum
6. Combined with automation mechanism such as robotic arm, it can realize the automation of processing.
Details of vacuum laser welding
1. Laser welding head

2. Operation interface
Multilingual intelligent control panel, flexible adjustment of welding parameters, multiple sets of welding parameter libraries, cumulative timing of light output, etc.
3. Automatic wire feeding system
Touch screen design, automatic wire filling, fully digital design, supports stainless steel and aluminum wires with diameters of 0.8mm, 1.0mm, 1.2mm, 1.6mm, and 2.0mm.
4. Laser source
We use custom-made fiber with a minimum core diameter of 20um, which has deeper penetration depth and a laser lifespan of up to 100,000 hours. It is maintenance-free and has Bluetooth functionality.
5. Chiller
Dual-cycle water cooling system provides better cooling for the laser source and welding head. The temperature control sensor uses imported brands.

3. Simple operation, easy to get started, no need for professional welders.
4. fast welding speed, efficiency is more than 5 times of arc welding.
5. beautiful welded seam, small deformation, save the cost of subsequent grinding and shaping.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.
Uses of Laser Welding Machines
With the continuous development of laser welding technology, the use of laser welding machine is more and more extensive.
1. welding: laser welding machine main welding object for the metal, such as stainless steel, copper, aluminum, gold, silver, titanium, nickel, tin, chromium, niobium, carbon steel, mold steel, galvanized sheet, etc., suitable for plane, straight line, arc, and any shape of the weld, multi-angle to carry out the welding work to meet the user's personalized welding needs.
2. cutting: welding and cutting are often inseparable, laser welding machine will combine the functions of the two together, laser welding machine can be used for laser cutting of metal materials, such as copper, aluminum, stainless steel, carbon steel, galvanized plate, etc., to meet the conventional thin plate cutting needs.
3. Cleaning: the use of laser welding machine for cleaning easy to use and flexible, able to remove all types of workpiece surface rust, oxides and grease and dirt, etc., in the use of hand-held laser welding machine for cleaning, you need to avoid the laser beam irradiation to the human body causing injury.
4. Weld channel cleaning: can effectively remove the welding process generated by the oxides, welding slag, oil, dust and other impurities, so that the weld surface becomes clean. This not only helps to improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning is highly accurate and controllable, allowing the weld surface to be thoroughly cleaned without damaging the base metal.
Welding method
A wide range of welding methods are available for welding at any angle, including overlay, butt, vertical, fillet, internal, external, etc. These methods can be used for a variety of workpieces, including complex welds and irregularly shaped workpieces, especially larger ones. These methods can be used to weld a wide variety of workpieces, including complex weld seams and irregularly shaped workpieces, especially larger workpieces.
