Due to its advantages of high energy density, high voltage, environmental protection, long life and quick charging, lithium battery is favored by 3C digital, power tools and other industries, and its contribution to the new energy vehicle industry is particularly outstanding. As the core component of new energy vehicle, the power battery is of direct quality

The vehicle performance, equipment precision and automation level will directly affect the production efficiency and consistency of the product. As an alternative to traditional welding technology, laser welding technology has been widely used in lithium electric manufacturing equipment. Firstly, laser welding has high energy density, small welding deformation and thermal shadow

Small ring area, can effectively improve the precision of production, weld smooth without impurities, uniform density, no additional grinding work; Secondly, laser welding can be precisely controlled, focusing spot is small, high precision positioning, with the robot arm easy to achieve automatic production.

Laser welding process:

Welding is a very important manufacturing process from lithium battery cell manufacturing to battery PACK group manufacturing. The conductivity, strength, air tightness, metal fatigue and corrosion resistance of lithium battery are typical evaluation standards for battery welding quality.

The selection of welding method and welding process will directly affect the cost, quality, safety and battery consistency. Among the many welding methods, laser welding stands out with the following advantages: first, laser welding can be effective due to its high energy density, small welding deformation and small heat affected area

To improve the precision of workpiece, weld smooth without impurities, uniform density, no additional grinding work; Secondly, laser welding can be precisely controlled, focusing spot small, high precision positioning, with the robot arm easy to achieve automation, improve welding efficiency, reduce working hours.
