Amada Miyachi Europe says it offers a range of resistance and laser welding capabilities for manufacturing battery packs for hybrid and electric vehicles. These include six laser welding technologies, four resistance welding technologies and micro-arc welding (also known as pulse-arc). The company says its application experts can recommend the right system based on the battery type, tab material and thickness, and required production volume, and that these systems are suited for integration into production lines.
Among the available technologies is the new Miyachi Eapro Jupiter Battery welding system, said to be suitable for welding cylindrical and prismatic batteries, pouch cells, and ultra-capacitors. It’s claimed this new module combines the advantages of resistance welding and laser welding into one battery tab welding system. The battery welding head uses an integrated tab down holder to ensure zero air gap between the tab and the battery pole.
