Vacuum Laser Welding

Integrated design, the laser, water tank and control part are combined together. It occupies a small area and has low site requirements. It is equipped with moving pulleys. The work position can be adjusted at any time according to the on-site requirements, which is convenient and flexible. The handheld welding head has a 10-meter-long transmission optical fiber, breaking through the limitations of the workbench and reaching a wider welding range. It is suitable for various complex welds and can perform laser welding on any part and angle of the workpiece.

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

Lightweight, only 0.8KG, flexible and convenient for welding metal parts of any shape, adjustable weld width, capable of long-distance welding up to 10 meters. Equipped with a safety temperature monitoring system.

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.

6. Welding connection fiber

The 10-meter-long optical cable adopts an integrated design, effectively avoiding damage to the fiber and problems caused by moisture, greatly improving the service life of the laser components.

Advantages of vacuum laser welding


1. Handheld operation welding, flexible and convenient, can be any shape, any angle welding.
2. Compact equipment, easy to move. Not only is it easy to weld large workpieces over long distances, but it can also be used for outdoor welding operations.
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.

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.

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.
