True 4-in-1 Function

● Welding

Laser welding has fast speed, small weld width and depth, small thermal shock area, small deformation, smooth and beautiful weld, high welding quality, no pores, accurate control, stable welding quality, no need for treatment or simple treatment after welding.

It can realize welding at any angle, suitable for welding of planes, straight lines, arcs and any shapes, and can complete welding well in various complex environments. It has high production efficiency and has more obvious advantages than traditional argon arc welding, electric welding and other processes.

● Cleaning

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized, and the rust, oxide layer, oil stains, etc. on the surface of the material can be effectively removed without destroying the surface characteristics. It has the characteristics of non-contact, does not require cleaning fluid, and can replace professional cleaning equipment.

● Cutting

Simple cutting can be performed, 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 cleaning

It can effectively remove impurities such as oxides, welding slag, oil, dust, etc. generated during welding, making the weld surface clean. This not only helps to improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning has high precision and controllability, and can thoroughly clean the weld surface without damaging the parent material.
