What are the advantages and disadvantages of laser welding machine?

 Advantages of laser welding machine: 

1. It can weld refractory materials such as titanium, quartz, etc., and can weld heterosexual materials with good effect.

2. It can be welded at room temperature or under special conditions, and the laser welding machine is simple. For example, when a laser passes through an electromagnetic field, the beam does not shift; The laser can be welded in vacuum, air and certain gas environments, and can be welded through glass or materials that are transparent to the beam.

3. The laser beam is easy to realize the beam splitting according to time and space, and can carry out multi-beam processing and multi-station processing at the same time, for more precise welding

4. It can weld the parts that are difficult to access, and implement non-contact long-distance welding with great flexibility. Especially in recent years, optical fiber transmission technology has been adopted in YAG laser processing technology, so that laser welding technology has been more widely promoted and applied.

5. Fast speed, large depth and small deformation.

6. Micro welding can be performed. The laser beam can obtain a small spot after focusing, and can be positioned, and can be applied to the mass automatic production of micro and small workpiece welding.

7. After laser focusing, the power density is high, and the depth-to-width ratio can reach 5:1 and the height can reach 10:1 when welding high-power devices.

Disadvantages of laser welding machine:

1. The position of the beam on the workpiece should not be significantly offset. This is because the spot after laser focusing is small, the weld is narrow, and the metal material is filled.

2. The laser and its related systems have a high cost and a large one-time investment.
