Laser welding is a process that uses the radiant energy of the laser to achieve effective welding. Its working principle is: the laser active medium is excite by a specific method to reciprocate in the resonant cavity, thereby forming an excite radiation beam. When the beam and the workpiece when contacte, its energy is absorbe by the workpiece, and welding can be performe when the temperature reaches the melting point of the material.

Advantages of laser welding machine
1. Micro welding
The laser beam can focuse to obtain a very small spot. Because it is not affected by the magnetic field and can accurately positione, it can micro-welde, which is suitable for the assembly welding of micro and small workpieces produce by large-volume automate production.
2. No loss
Because laser welding is a non-contact process, there are no problems such as tool wear and tool replacement. At the same time, it does not require the use of electrodes, so there is no concern about electrode contamination or damage, and it is easy to perform high-speed welding with automation. It can also be control by digital or computer.
3. Flexible and changeable
It can be use to weld refractory materials such as high melting point metals, and can even use to weld non-metallic materials such as ceramics and plexiglass. Laser welding machine can weld special-shape materials with good results and great flexibility. The machine can be use for welding inaccessible parts Perform non-contact long-distance welding.
4. Fast speed, high power and small deformation
Laser welding is a non-contact welding. It does not require pressure during the operation. The machine has fast welding speed, high efficiency, large depth, small residual stress and deformation. Laser welding machine can weld at room temperature or under special conditions (such as a closed space). Welding equipment Simple, does not produce X-rays.
