● Welding
Laser welding features fast speed, narrow weld seam, low thermal impact and minimal deformation. It delivers smooth, pore‑free, high‑quality welds with precise and stable control, requiring little or no post‑weld treatment. Supporting multi‑angle welding for planes, curves and complex‑shaped workpieces, it performs well in diverse working conditions and boasts higher efficiency compared with traditional argon arc welding and electric welding.
● Cleaning
By changing the laser nozzle and cleaning lens, the machine achieves material surface cleaning. It efficiently removes rust, oxide layers and oil stains without damaging substrate surfaces. This non‑contact cleaning needs no cleaning agents and can substitute dedicated cleaning equipment.
● Cutting
Equipped with switchable welding and cutting functions, the machine supports easy mode conversion simply by replacing the copper nozzle. It can cut common metal sheets including carbon steel, stainless steel, iron and aluminum alloy, with a maximum cutting thickness of 2 mm.
● Weld cleaning
It effectively clears welding‑generated oxides, slag, oil and dust for clean weld surfaces, improving weld quality, strength and appearance. With high precision and controllability, laser cleaning thoroughly treats welds without damaging base materials.
● Energy Storage Welding
It copes well with high‑energy‑demand welding tasks to guarantee consistent welding quality. Delivering massive energy in a short time, energy‑storage welding fits diverse metals, especially for high‑strength and precision welding scenarios.
2. The handheld welding gun replaces the previous fixed light path, which is more flexible and convenient, enables long-distance laser welding, and overcomes the limitations of the workbench travel space.
3. The handheld welding head is light and flexible, easy to operate, and can meet welding at various angles and positions.
4. Use infrared positioning for welding head position calibration and position verification during welding to ensure a more beautiful weld.
5. It has the dual protection function of water path and air path (patented technology), which effectively avoids damage to the laser lens or optical components due to operator misoperation, thus greatly reducing the machine failure rate and effectively extending the service life of the machine. The life of consumables.
6. Use infrared positioning to verify the position of the welding head during the welding process. The welding position is more accurate, the welding seam is smooth and beautiful, and it is easy to grind and polish. No post-welding treatment is required or only simple processing is required.
