The degree of automation of the laser welding machine is high, and the welding process is simple. Using laser welding machine to process workpiece can improve work efficiency, finished workpiece has beautiful appearance, small welding seam, large welding depth and high welding quality. Follow Qiaolian Cylion to learn about the application range of automatic laser welding machines.
Manufacturing
Tailored laser welding technology is widely used in foreign car manufacturing and continues to grow at a relatively high rate. The domestically produced and imported models also use some tailoring slab structures. Japan uses CO2 laser welding instead of flash butt welding for the connection of rolled steel coils in the steel industry. In the research of ultra-thin plate welding, such as foils with a thickness of less than 100 microns, fusion welding cannot be performed, but through YAG with special output power waveform The success of laser welding shows the bright future of laser welding. Japan has also successfully developed, for the first time in the world, the use of YAG laser welding for the maintenance of thin tubes of steam generators in nuclear reactors, and has also carried out gear laser welding technology in China.
Powder metallurgy
With the continuous development of science and technology, many industrial technologies have special requirements for materials, and materials manufactured by smelting methods can no longer meet the needs. Due to the special properties and manufacturing advantages of powder metallurgy materials, traditional smelting materials are being replaced in some fields such as automobiles, aircraft, and tool and cutting tools manufacturing. With the increasing development of powder metallurgy materials, it is connected with other parts. It is increasingly prominent, which limits the application of powder metallurgy materials.
Laser welding has entered the field of powder metallurgy material processing with its unique advantages, which has opened up new prospects for the application of powder metallurgy materials. For example, the brazing method commonly used in powder metallurgy materials is used to weld diamond. In particular, it cannot adapt to high temperature and high strength requirements and cause the solder to melt and fall off. Using laser welding can improve the welding strength and high temperature resistance.
Auto industry
According to the characteristics of large batches and high degree of automation in the automobile industry, laser welding equipment is developing in the direction of high power and multi-channel. In terms of technology, the Sandia National Laboratory of the United States and PrattWitney have jointly conducted research on adding powder metal and metal wire in the laser welding process. The Institute of Applied Beam Technology in Bremen, Germany has carried out a lot of research on the use of laser welding of aluminum alloy body frames. It is believed that adding filler metal to the weld will help to eliminate hot cracks, increase welding speed, and solve tolerance problems, and the developed production line has been put into production in the factory.
Electronics industry
Laser welding has been widely used in the electronics industry, especially in the microelectronics industry. Due to the small heat-affected zone, rapid heating concentration and low thermal stress of laser welding, it shows unique advantages in the packaging of integrated circuits and semiconductor device housings. In the development of vacuum devices, laser welding has also been applied, such as Molybdenum focusing electrode and stainless steel support ring, fast hot cathode filament assembly, etc. The thickness of the elastic thin-walled corrugated sheet in the sensor or thermostat is 0.05-0.1mm, which is difficult to solve by traditional welding methods. TIG welding is easy to weld through, the plasma stability is poor, and there are many influencing factors. Laser welding has a good effect and has been widely used. Applications.
Other areas
In other industries, laser welding is also gradually increasing, especially in the welding of special materials, many researches have been carried out in China, such as new laser welding technologies such as BT20 titanium alloy, HEl30 alloy, Li-ion battery, etc.
