● 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.
