1. Small, beautiful and smooth weld seam, no pores, high weld depth ratio and high welding quality, the toughness after welding is comparable to that of the parent material.
2. Simple operation, large laser power, high efficiency, no consumables, long-term processing is possible;
3. Spot welding, butt welding and precision welding can be realized for thin-walled materials and precision parts;
4. Obvious advantages in special-shaped welding, splicing welding and spot welding, large laser power is sufficient to weld metals that is not easily to be melted such as gold, silver and copper. It can weld small and delicate geometric areas.
