Welding is a crucial step in the manufacturing of lithium batteries, and laser welding provides a solution for re-melting issues in arc welding. The battery structure comprises materials such as steel, aluminum, copper, and nickel, which can be easily welded using laser technology. Lithium battery laser welding automation lines automate the manufacturing process from cell loading to welding inspection. These lines include material transmission and adaptive systems, visual positioning systems, and MES manufacturing execution management, which are crucial for the efficient production of small batches and multi-variety forms.90+ TEYU water chiller models can apply to more than 100 manufacturing and processing industries. And water chiller CW-6300 can provide efficient and reliable cooling for laser welding of lithium batteries, helping to upgrade the automated production line of power batteries for laser welding.
