Laser welding machine is a kind of machine used in the field of welding, which is one of the important aspects of the application of laser material processing technology. According to its working mode, it can be divided into laser mold and welding machine, automatic laser welding machine, laser spot welding machine, optical fiber laser welding machine, etc. laser welding equipment has penetrated into our life, and has been more and more widely used, especially in many industries, It has gradually replaced the traditional welding method.
1. Manufacturing application of metal laser welding machine
Laser welding machines are widely used in automobile manufacturing at home and abroad. In Japan, CO2 laser welding machine has been used to replace flash butt welding for the connection of rolled steel coils in the steel industry. In the research of ultra-thin plate welding, such as foil with a thickness of less than 100 microns, there is no way to fuse welding, but YAG laser welding with special output power waveform has been successful, showing the broad future of laser welding.
2. Powder metallurgy
With the continuous development of science and technology, many industrial technologies have special requirements for materials, and the materials made by traditional technology can no longer meet the requirements.
Laser welding machine has entered the field of powder metallurgy material processing, which has brought new development prospects for the application of powder metallurgy materials. For example, the brazing method commonly used in the connection of powder metallurgy materials is used to weld diamonds. Because the bonding strength is low, the heat affected zone is wide, especially unable to adapt to high temperature and high strength requirements, resulting in the melting and falling off of solder, the use of laser welding machine can improve the welding strength and high temperature resistance.
3. Electronics Industry
Laser welding machine has been widely used in electronic industry. Because of its small heat affected zone, rapid heating concentration and low thermal stress, laser welding has shown its unique advantages in the packaging of integrated circuits and semiconductor device shells. In the development of vacuum devices, laser welding has also been applied.
The thickness of the elastic thin-wall corrugated sheet in the sensor or temperature controller is 0.05-0.1mm, which is difficult to solve by using traditional welding methods. TIG welding is easy to penetrate, the plasma stability is poor, and there are many influencing factors. However, laser welding has a good effect, which is widely used.
