Collector & Cap Welding

A joining solution for forming electrical connections between the collector and cap in prismatic battery cells.

Automatic positioning of collectors and caps

Controlled penetration depth and width with low spatter and minimal thermal impact

Low-resistance joints for stable current transmission

Weld quality verification with automatic NG rejection

Specification

Cell loading → Collector & cap alignment → Laser welding → Post-weld inspection → NG rejection

Prismatic cells (Jelly-Roll type and stacked-type electrode structures)
