1. Non-contact processing, no external force on the welded parts.
2. The laser energy is highly concentrated, with little influence and small deformation.
3. It can weld high melting point, refractory and difficult to weld metals, and can realize the welding between certain dissimilar materials.
4. The welding process has no pollution to the environment, it can be directly welded in the air, and the process is simple.
5. The welding spot is small, the welding seam is narrow, neat and beautiful, no need to deal with after welding or only simple process. The weld seam has a uniform structure, fewer pores, and fewer defects, which can reduce and optimize the material impurities. The mechanical strength of the weld seam is often higher than the mechanical strength of the material. The mechanical properties, corrosion resistance and electromagnetic properties of laser welding are superior to conventional welding methods.
6. The laser can be precisely controlled, the focus spot is small, and it can be positioned with high precision to achieve precise processing.
