Amada Miyachi Europe offers six laser welding technologies, four resistance welding technologies and micro-arc welding (also known as pulse-arc). Application experts recommend the right system based on the battery type, tab material and thickness, and required production volume. These systems are suited for integration into production lines. They help customers develop a stable and reproducible process and improve quality control.


Among the available technologies is the new Miyachi EAPRO Jupiter Battery Welding system, ideal for welding cylindrical and prismatic batteries, pouch cells, and ultra-capacitors. The module combines the advantages of resistance welding and laser welding into one complete 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. No additional tooling is required, resulting in fast, reliable welding of highly conductive materials like copper and aluminium. With weld speeds of less than one second and an integrated shielding gas and fume extraction nozzle, the module can be integrated into Amada Miyachi Europe’s systems platforms and automated in-line systems. An OEM version of this module is offered for integration into third party production lines.
