As we all know, laser welding equipment has been widely used in all walks of life, such as: machinery manufacturing, precision electronics, jewelry, jewelry, battery, hardware and plastic, digital products and kitchen bathroom and other industries. Today, I will introduce you to the difference of laser welding equipment where the difference.

As a national strategic emerging industry, new energy power battery plays a pivotal role in the implementation of the national innovation-driven development strategy. In recent years, the new energy power battery industry has developed rapidly, although the market share in the world has reached the top in the world. With the rapid development of science and technology, laser welding machine in various fields have a great development.

At present, the square aluminum shell battery occupies a large proportion in the whole power battery. In the welding process, due to the particularity of the aluminum alloy shell, problems such as bulge and pores appear in the welding process, especially in the corner part.

Xinde Laser believes that welding is a very critical process from the production of lithium cell to the assembly of PACK. Its conductivity, strength, air tightness, metal fatigue and corrosion resistance are typical indicators to measure the welding quality of batteries. Lithium battery laser welding machine manufacturer Xin De laser believes that: choose the right welding mode and process, will be directly related to the cost of the battery, quality, safety and stability of the battery. Because of its safety, reliability, process precision, environmental protection and other advantages, it is preferred in many welding industries.

Laser welding technology is to focus the laser energy on a beam, and then processed into a weld on the workpiece, laser welding mainly includes laser welding host, laser welding head, cable, cooling system. Laser welding machine includes CO2 laser, fiber laser, disc YAG laser, semiconductor laser and so on.

Because of the continuous improvement and innovation of the new technology of manufacturing industry in our country, laser welding is now widely used by some high precision and high-density manufacturing industries, such as medical instruments, precision manufacturing, automotive, metallurgy and other industries. But in the application of laser welding, we should also pay attention to its advantages and disadvantages, that is, we must pay attention to and understand in the operation:

Battery explosion-proof valve welding: battery explosion-proof valve is a thin-walled valve body installed on the battery sealing plate, in the case of battery pressure greater than the specified, will make the valve body fracture, so as to prevent the battery explosion. Safety valve design is very delicate, this process requires very high laser welding technology. Before the use of continuous laser welding, the use of pulsed laser welding battery explosion-proof valve, the overlap and cover between solder joints and solder joints can achieve continuous welding, but its welding efficiency and sealing are relatively poor. Continuous laser welding technology is used to ensure the stability, efficiency and yield of welding products.
