Can aluminum alloy be welded by laser welding technology?

With the national pursuit of energy-saving development of the economy in recent years, the need for aluminum alloys has gone up a notch. Research results show that the use of aluminum alloy materials to properly reduce the weight of the car we can reduce fuel consumption by 37%;battery pilot line the load of the suspension device by 18%; vibration intensity by 5%. In the major automobile factories to increase the aluminum alloy processing research and development and manufacturing resources, aluminum alloy welding has become a have to in order to solve the basic problem. Can laser welding construction technicians improve welding aluminum alloy materials?

Can laser welding technology weld aluminum alloy materials? Of course it is possible to weld. With the increasing popularity of laser processing applications, the use of laser welding of aluminum alloys, heat input is small, the heat source is concentrated, especially after the emergence of fiber lasers, laser welding of aluminum alloys, the energy density is more concentrated, the laser wavelength is shorter, and the high reflectivity has been improved.laser welding machine for lithium ion batteries Laser wire filling, laser -MIG composite welding and double-point laser welding can improve the forming effect and welding quality of aluminum alloy. As aluminum alloy has the characteristics of lively, easy oxidation, easy to attach a large amount of dust and moisture on the surface, the surface of laser fast welding aluminum alloy is easy to residual adhesion, which affects the quality of aluminum alloy and welding effect.ESS lithium battery machine Therefore, before aluminum alloy welding, the surface of the aluminum alloy needs to be cleaned, and the surface of the oil and so on. At the same time, to prevent safety threats such as explosions caused by oxidation in the welding process, it is also necessary to thoroughly clean the oxide film on the surface of the metal and completely remove the oxide film.

The use of dual-beam laser welding can significantly improve the gas holes, mainly because the dual-beam formation of larger holes, improving the stability of the holes, which is conducive to the escape of gas. Compared with serial dual-beam welding, the temperature gradient in the molten pool is smaller, the solidification rate of the liquid metal is lower, the gas bubble escapes for a longer time, and the tendency of porosity is reduced.

Laser welding technology can weld aluminum alloy materials. Aluminum and aluminum alloys both have excellent properties such as high specific strength and corrosion resistance, and are widely used in many industries, especially in the defense industry, machinery and other industries. Aluminum alloy belongs to non-ferrous metals, which need to be welded in the application process. Therefore, with the rapid development of science and technology, the research on aluminum alloy welding technology is more and more in-depth. Therefore, laser welding technology is a great progress in science and technology.
