Learn MoreFusion 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.
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.
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
The search was then performed using Uppsala University's Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
Thus the welding method has a minimal impact on the battery as there are no catalyzing reactions in the battery caused by the heat. On the other hand deformation may occur if too great of a welding force is applied by the electrodes. This deformation may alter the temperature distribution and hinder the current from flowing the shortest path.
The purpose of this project is to conduct a comparative literature study of different welding techniques for welding batteries. The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality.
