Advantages of yag laser welding machine

1. Four-in-one: Quickly switch between four modes: cleaning, welding, cutting, and weld cleaning.

2. The handheld welding gun replaces the previous fixed optical path, making it more flexible and convenient, achieving long-distance laser welding, and overcoming the limitations of workspace travel.

3. The handheld welding head is lightweight, flexible, and easy to operate, meeting the requirements of welding at various angles and positions.

4. The use of infrared positioning is used for welding head position alignment and verification during welding, ensuring a more aesthetic weld seam.

5. Equipped with dual protection functions of water and air circuits (patented technology), effectively avoiding damage to laser lenses or optical components caused by operator error, greatly reducing machine failure rate and extending the life of consumables.

6. The use of infrared positioning verifies the welding head position during the welding process. The welding position is more accurate, the weld seam is smooth and beautiful, easy to polish, and no post-welding treatment is required or only simple treatment is needed.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.

Other optional features

● 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.

Comparison of handheld laser welder and tig welding

1. Comparison of energy consumption

Compared with traditional arc welding, the handheld laser welding machine saves about 80%-90% of electric energy, and the processing cost can be reduced by about 30%.

2. Welding effect comparison

Laser handheld welding can complete dissimilar steel and dissimilar metal welding. Fast speed, small deformation, small heat affected zone. Weld seam is beautiful, flat, no/few porosity, no pollution. Handheld laser welding machine can perform tiny open parts and precision welding.

3. Comparison of follow-up process

Laser handheld welding with low heat input, workpiece deformation is small, you can get a beautiful welded surface, no need or only need to be briefly processed (depending on the welding surface effect requirements). Handheld laser welding machines can greatly reduce the labor cost of the huge polishing and leveling process.

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
