Fusion welding, specifically using electron beams or lasers, is the best method for welding battery components. Both electron beam and laser welding offer high power densities, pinpoint accuracy, and are well-suited for automated welding processes and small, miniature weld applications.
This provides a lot of flexibility, making it possible to weld any joint geometry as well as custom weld patterns. Fiber lasers are the lasers of choice for battery welding. They can weld thin or thick tabs, and process copper, aluminum, steel, and nickel as well as dissimilar materials.
Selecting the appropriate battery pack welding technology to weld battery tabs involves many considerations, including materials to be joined, joint geometry, weld access, cycle time and budget, as well as manufacturing flow and production requirements. Fiber laser welding
Battery applications often involve welding dissimilar metals, such as copper to nickel, which can be problematic in welding. Commonly used materials in battery construction include copper, aluminum, and nickel.
Fiber lasers are the lasers of choice for battery welding. They can weld thin or thick tabs, and process copper, aluminum, steel, and nickel as well as dissimilar materials. Laser welding can be used to make tab-to-busbar connections as well as foil-to-tab welds. You can see an example of busbar connections below.
Resistance welding Resistance welding is the most cost-effective method to weld battery tabs, using both DC inverter closed loop and capacitor discharge power supplies.
