Laser welding machine is one of the welding equipment and has been one of the fastest developing welding methods in recent years. Laser welding uses high energy laser pulses to locally heat the small area of the workpiece. The energy of the laser radiation diffuses towards the inside of the workpiece through heat conduction, melting the workpiece and forming a specific molten pool. Due to the high power density and fast energy release of laser welding, its processing efficiency is much higher than that of traditional welding methods.
After the laser is focused, the spot size becomes small. During the welding process, it can provide better adhesion between two materials, without causing damage or deformation to the surface of the material, and without the need for post-welding treatment.
Laser welding has been widely used in the electronic industry, especially in precision parts of microelectronics. Because laser welding has a small heat-affected zone, rapid and concentrated heating, and low thermal stress, it has shown unique advantages in the packaging of integrated circuits and semiconductor devices. Elastic thin-walled corrugated sheets used in sensors or temperature controllers have a thickness of 0.05-0.1mm, which is difficult to solve by traditional welding methods. TIG welding is easy to puncture, plasma has poor stability, and there are many factors that affect it. Laser welding works well and has been widely used.
The laser for welding precision parts can be bent and transmitted through optical methods such as optical fibers and prisms, which is suitable for welding in parts that are difficult to reach by other welding methods, such as tiny components, and can even weld through transparent materials.
It has a high energy density and can achieve high-speed welding with a small heat-affected zone and little welding deformation. It is particularly suitable for welding heat-sensitive materials.
Laser welding for precision parts is not affected by electromagnetic fields, does not produce X-rays, and does not require vacuum protection, so it can be used in the welding of large structures.
Insulated conductors can be directly welded without stripping insulation layers in advance. It can also weld dissimilar materials with different physical properties.
Ningbo Xihe Automation Equipment Co., Ltd. can customize various non-standard automatic welding equipment according to different customer needs. The company has a professional R&D and production team and is equipped with high-precision CNC machines, grinders, milling machines, and machining centers.
In the spirit of honesty and pioneering, we will promote a "five-in-one" business model that integrates scientific research, production, brand, market, and after-sales service. We sincerely cooperate with new and old customers for common development.
