The main advantages of laser welding:

1. Fast speed, large depth and small deformation.

2. It can be welded at room temperature or under special conditions, and the welding equipment is simple. For example, when the laser passes through an electromagnetic field, the beam will not shift; the laser can be welded in vacuum, air and certain gas environments, and can pass through glass or weld materials with a bright beam.

3. It can weld refractory materials such as titanium, quartz, etc., and can weld heterogeneous materials with good results.

4. After the laser is assembled, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the highest can reach 10:1.

5. Micro welding is possible. The laser beam can obtain a small spot after being concentrated, and can be accurately positioned, which can be used in the assembly welding of micro and small workpieces produced automatically in large quantities.

6. It can weld hard-to-reach parts, and implement non-touch long-distance welding, which has great flexibility. Especially in recent years, the use of optical fiber transmission technology in YAG laser processing technology has made laser welding technology more widely promoted and applied.

7. The laser beam is easy to split the beam according to time and space, and can process multiple beams together and multi-station processing, which provides conditions for finer welding.
