Introduction to the Process of Power Battery Welding Machine
2022-11-29
Laser welding, as a very important process in battery production, has a significant impact on the consistency, stability, and safety of batteries.Power battery welding machineThere are many welding points, the process difficulty is high, and the requirements for welding technology are even higher. Precise laser welding can greatly improve the safety, reliability, and service life of automotive power batteries, which will provide important guarantees for the development of future automotive power technology. The welding of power battery casings mainly includes side welding and top welding, each with its own advantages and disadvantages. However, due to the special material of aluminum batteries, issues such as bulging and porosity are prone to occur, and square battery welding is likely to encounter problems at the corners.
The welding of power battery welding machines is a fusion manufacturing process that decomposes raw materials such as positive and negative electrode materials, separators, and electrolytes into components, and is a key process in the entire power battery production process. All raw materials are welded into battery cells and battery pack modules, which can be directly used in traditional consumer electronics, electronic tools, electric bicycles, energy storage stations, and new energy vehicles.
Advantages of power battery welding machine products:
1. Fast speed, large depth, and small deformation.
2. Can weld at room temperature or under special conditions, with simple welding equipment. For example, when the laser passes through an electromagnetic field, the beam will not deviate; laser welding can be performed in vacuum, air, and certain gas environments, and can be conducted using glass or materials transparent to the beam.
3. Can weld refractory materials such as titanium and other materials. Can weld dissimilar materials with good results.
4. After laser focusing, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1 and 10:1.
5. Can perform micro-welding. After focusing the laser beam, a very small light spot can be obtained, and precise positioning is possible. It can be applied to the assembly welding of small workpieces in large-scale automated production.
6. Can perform non-contact long-distance welding in hard-to-reach areas, providing great flexibility. Especially in recent years, the use of fiber transmission technology in YAG laser processing technology has led to a wider promotion and application of laser welding technology.
7. The laser beam is easy to split in time and space, which can be used for simultaneous processing with multiple beams and multi-station processing, providing conditions for more precise welding.
