New energy vehicle is green and pollution-free, and will develop rapidly in the next few years. The structure of automobile power battery covers a variety of materials, and the requirements for welding are very high. The assembled power battery needs to pass the leak test, and the battery with an unqualified leak rate will be rejected. Laser welding can greatly reduce the defect rate in power battery manufacturing.The mainly used of battery products are copper and aluminum. Both copper and aluminum transfer heat quickly, the reflectivity to the laser is very high and the thickness of the connecting piece is relatively large, a kilowatt-level high-power laser is often used. The kilowatt-class laser needs to achieve high-precision welding, and the long-term operation requires very high heat dissipation and temperature control. S&A fiber laser chiller adopts dual temperature and dual control method to provide a full range of temperature control solutions for fiber lasers. At the same time, you can manually set the water temperature according to actual needs, or switch to the intelligent temperature control working mode. It has the advantages of long life, environmental protection and energy saving, can meet the production needs of fiber laser equipment welding power batteries.
