Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.
Welding is a vitally important family of joining techniques for EV battery systems. A large battery might need thousands of individual connections, joining the positive and negative terminals of cells together in combinations of parallel and series blocks to form modules and packs of the required voltage and capacity.
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
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.
Of these, laser and ultrasonic welding processes dominate in EV battery manufacture – with laser welding the preferred solution for mass production – and continue to be improved and refined. “We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech.

The production of Li-ion batteries requires multiple welding processes. Welded contact connections between the individual battery cells, for example, have proven to be more reliable, sustainable and above all cost-effective than bolted contacts or the use of bimetallic busbars.. The boxes of the rigid battery geometries are also welded, because they have to be gas-tight up to …
Laser welding technology employs high-intensity laser beams to create strong and precise welds in critical battery components. This cutting-edge process minimizes the heat-affected zone, reducing thermal damage to sensitive materials.
While laser welding is known for its ability to produce high-quality welds at high speeds, integrating this technology into EV battery production lines presents unique challenges. EV manufacturers need to work with laser and automation experts that know how to address these challenges if they want to achieve a high yield and produce at a high rate.
