Laser welding is a method of using a high energy laser to form an internal structure on the surface of the processed product so that two separated products can be atomically connected. Compared with conventional argon arc welding and resistance welding, laser welding technology has great advantages. First, there are fewer heat-affected zones, second, non-contact processing, and third, high processing efficiency. Xinde laser welding machine in the field of new energy lithium battery, has been widely used in the pole ear, cell shell, soft joint, explosion-proof valve, battery module and so on.

As we all know, the power source of new energy vehicles is lithium battery, its performance determines its endurance and driving range, and the quality of its manufacturing process will directly affect the market performance of new energy vehicles. Therefore, to improve the performance of power batteries, many companies are using more advanced processing methods, such as laser technology.

Now, the new energy vehicles can reach the speed of 100 kilometers in a few seconds, which makes many people feel the fun of "super running". Hundreds of lithium-ion battery cells make up the high-speed driving power of new-energy vehicles. In the production of lithium batteries or battery packs, more than 20 processes use welding to achieve conductivity or sealing. The quality of welding is directly related to the safety of automobile.

With the development of technology and technology, laser will become a kind of non-contact flexible machining tool. Laser manufacturing will become a convenient, high-speed, environmental protection, energy saving advanced manufacturing technology, it will promote the development of our industrial technology, improve the technical level of the product, to adapt to the development of national manufacturing industry. Xinde Laser has a wide range of research and application experience in the field of new energy lithium, in precision electronics, automotive parts and other aspects of the application of many examples. Xinde Laser will further carry out laser technology research and development and automation integration, to make China's automation industry bigger and stronger.
