Manufacturing application
Laser welding machine is widely used in automobile manufacturing at home and abroad. In Japan, the steel industry uses CO2 laser welder to connect rolled coils instead of flash butt welding. In the research of ultra-thin plate welding, if the foil with the thickness below 100 micron can't be welded, but the YAG laser welding with special output power waveform is successful, which shows the broad prospect of laser welding.
Powder metallurgy field
With the continuous development of science and technology, many industrial technologies have special requirements for materials, and the materials manufactured by traditional technologies can no longer meet the requirements. Laser welding machine enters the field of powder metallurgy materials processing, which brings 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. Due to the low bonding strength and wide heat affected zone, especially the requirement of high temperature and high strength, the solder melts and falls off. Using laser welding machine can improve welding strength and high temperature resistance.
electronic industry
Laser welding machine has been widely used in electronic industry. Because laser welding has the advantages of small heat affected zone, fast heating concentration and low thermal stress, it has shown unique advantages in the packaging of integrated circuits and semiconductor devices, and has also been applied in the development of vacuum devices. The thickness of elastic thin-walled corrugated sheet in sensor or thermostat is 0.05-0. 1mm, which is difficult to solve by traditional welding method. TIG welding is easy to penetrate, the plasma stability is not good, and there are many influencing factors, so laser welding is effective and widely used.
automotive industry
Nowadays, the laser welding machine production line has appeared in the automobile manufacturing industry on a large scale and has become one of the outstanding achievements of the automobile manufacturing industry. Many automobile manufacturers have adopted laser welding and cutting processes. High-strength steel laser welding components are more and more used in automobile body manufacturing because of their excellent performance. Due to the large batch of automobile industry and high degree of automation, laser welding equipment will develop in the direction of high power and multi-channel.
