Laser welding machine is one of the welding equipment and one of the welding methods that have been widely used in recent years. Laser welding is to use high-energy laser pulses to locally heat the small area of the workpiece. The energy radiated by the laser is directed to the internal diffusion of the workpiece through heat transfer, and the workpiece is melted to form a specific molten pool. Because of the high power density and fast energy release of laser welding, Therefore, the processing efficiency is much higher than that of traditional welding methods. After the laser is focused, the light spot is small. In the welding process, it can make the adhesion between the two materials better, without causing damage and deformation to the surface of the material, and without post-processing the weld.
Laser welding is widely used in electronic industry, especially in micro electronic precision parts. Due to the small heat affected zone, rapid heating concentration and low thermal stress of laser welding, it is showing unique advantages in the packaging of integrated circuits and semiconductor device shells. The thickness of elastic thin wall corrugated sheets in sensors or temperature controllers is 0.05-0.1mm, which is difficult to solve with traditional welding methods. TIG welding is easy to penetrate, and the plasma stability is poor. Laser welding has a good effect due to many factors, It has been widely used.
Main advantages of laser welding machine for precision parts
1. The laser for precision parts welding can be bent and transmitted through optical methods such as optical fiber and prism. It is suitable for welding micro parts and parts that are difficult to reach by other welding methods, and can also be welded through transparent materials.
2. With high energy density, high-speed welding can be realized, and the heat affected zone and welding deformation are very small, which is especially suitable for welding of heat sensitive materials.
The laser used for welding precision parts is not affected by electromagnetic field, does not produce X-ray, and does not need vacuum protection. It can be used for welding large structures.
4. The insulating conductor can be directly welded without stripping the insulating layer in advance; It can also weld dissimilar materials with large differences in physical properties.
