Features of laser handheld welding gun


1. Utilize infrared positioning to verify the position of the welding head and confirm the position of the welding process. This results in a more precise welding position, a smooth and aesthetically pleasing weld seam, and facilitates easy grinding and polishing. Additionally, it eliminates the need for extensive treatment processes after welding, or may require only simple treatment.

2. Our self-developed handheld welding head is equipped with various safety alarm devices, ensuring easy and flexible operation.

3. The equipment is furnished with a high precision wire feeder, a touch capacitive screen, a 220V drive, and an automatic wire feeding system. This enables more powerful wire feeding and eliminates the occurrence of wire jamming.

4. Suntop's patented technology water circulation protection system and auxiliary gas detection effectively prolong the lifespan of the laser lens and prevent damage to optical components caused by improper operation.

5. It is equipped with a 10m imported optical fiber, which overcomes the limitations of table space and allows for flexible and convenient usage in outdoor and long-distance welding scenarios.

6. As a standard feature, it is equipped with a variety of welding copper nozzles, including flat, inside, and outside angle nozzles. These can be easily replaced to accommodate different welding requirements and meet various welding needs.

Advantages of laser handheld welding gun


1. The welding speed is fast, 5-10 times faster than traditional argon arc welding, and the processing cost can be reduced by about 30%.

2. The operation is simple and easy to learn, with no technical threshold requirements. Ordinary workers can operate it after a short-term training, easily achieving high-quality welding results.

3. It is convenient and flexible to use, and the work station can be adjusted at any time. There is no need for a fixed work station, allowing for freedom and flexibility, suitable for various work environment scenarios.

4. It has a wide welding range, overcoming the limitations of the workbench space, and can achieve outdoor welding and long-distance welding.

5. It has multiple welding methods, allowing for welding at any angle, overlay welding, butt welding, vertical welding, fillet welding, inside corner welding, outside corner welding, etc. It can weld complex welds on various workpieces and larger irregular-shaped workpieces.

6. It has concentrated energy, small heat-affected zone, no deformation, no blackening, large welding depth, fine and beautiful welds, and strong and firm welding. The strength of the weld seam can reach or even exceed the strength of the base material itself.


Other optional functions of laser handheld welding gun


● Cleaning function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized, effectively removing rust spots, oxide layers, oil stains, etc. on the material surface without damaging the surface characteristics. It is non-contact and does not require cleaning fluid, so it can replace professional cleaning equipment.

Cutting function

Simple cutting is possible, welding and cutting can be switched freely, just change the welding copper nozzle to the cutting copper nozzle, which is very convenient.

It can cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other metal sheets with a maximum cutting thickness of about 2mm.

Weld bead cleaning function

It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.

Handheld laser welding and argon arc welding comparison


1. Energy consumption comparison: compared with traditional arc welding, handheld laser welding machine saves about 80% to 90% of electrical energy, and processing costs can be reduced by about 30%.

2. Comparison of welding effect: Laser handheld welding can complete the welding between metal and dissimilar metal. Fast speed, small deformation, small heat-affected zone. The welding seam is beautiful, flat, without/less porosity and no pollution. Handheld laser welding machine can perform tiny open parts and precision welding.

3. Comparison of subsequent processes: Handheld laser welding with low heat input and small deformation of the workpiece can result in a beautiful welded surface without or with only a brief treatment (depending on the welded surface effect requirements). Handheld laser welding machine can greatly reduce the huge polishing and leveling process consuming labor costs.


Application materials


Suitable for stainless steel, carbon steel, copper, aluminum, gold, silver, chromium, nickel, titanium and many other metals and alloys; also can be used for welding between a variety of dissimilar materials.


Application industry
