Principle of welding
Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material melts to form a specific molten pool.

Welding version of continuous fiber laser RFL-C2000H
It has higher photoelectric conversion efficiency, better and more stable beam quality, and stronger anti-high-reflection capability. At the same time, it introduces an optimized second-generation optical fiber transmission system, which has obvious advantages over other lasers of the same type in the market.
Features of laser welding
1. The welding speed is fast, 2-10 times faster than traditional welding, and one machine can save at least 2 welders a year.
2. The operation mode of the hand-held welding gun head enables the workpiece to be welded at any position and at any angle.
3. No need for welding table, small footprint, diversified welding products, and flexible product shapes.
4. Low welding cost, low energy and low maintenance cost.
5. Beautiful welding seam: the welding seam is smooth and beautiful without welding scars, the workpiece is not deformed, and the welding is firm, which reduces the follow-up grinding process and saves time and cost.
6. No consumables: laser welding without welding wire, less consumables, longer life, safer and more environmentally friendly.
