Smart monitoring of battery welding processes: Sensor systems for laser welding applications along the battery production chain: from cell to package

One of the key laser application areas in the e‐automotive industry is the welding of the battery. Sensor systems from Lessmüller Lasertechnik ensure reliable, high‐precision joining, which is vital in the assembly of any battery. Installed to various remote and fixed welding optics, the OCT, WELDCHECK, and WELDEYE sensor systems demonstrate real‐time monitoring capability with great accuracy and over a wide dynamic range, enabling faster, cost‐effective e‐automotive laser processes and streamlined production.
