Features of 1000w handheld fiber laser welding machine

1. Flexible and easy to operate, it can meet multi-angle and multi-position welding.

2. Equipped with 10m original imported optical fiber, it can be very flexible and convenient for outdoor welding.

3. Using infrared positioning to verify the position of the welding head and verify the position of the welding process. More accurate welding position, smooth and beautiful weld seam, easy to grind and polish, no treatment or only simple treatment process after welding.

4. No dead angle 360° micro welding, small spot, high power density, high positioning accuracy after laser beam focus, can be used for assembly welding of small and micro size workpieces, and realize automatic mass production.

5. Laser welding depth is deep, weld seam is firm, width is small, heat-affected zone is small, deformation is small, and welding speed is fast. It can realize complex welding between some dissimilar materials.

6. The system can store a variety of different process parameters, which can be switched at any time through the touch screen according to the processing demand, reducing the parameter debugging time.
