Addressing New Challenges in Laser and Resistance Welding for Battery Pack Assembly

Battery pack assembly is a critical process in manufacturing today, particularly as applications in the electric vehicle (EV), consumer electronics, and power tools energy storage industries demand increasingly robust and efficient connections. To meet these demands, manufacturers rely on advanced welding techniques – usually resistance welding or laser welding - to ensure the durability, reliability and performance of finished battery packs. As battery module/pack design advances to address the need for better efficiency, higher storage, and faster charge/discharge properties, new challenges arise for the welding process used to make them. Resistance and laser welding each provide unique advantages to address these challenges.
