In this video, we showcase Laserax's production-grade laser welding solution for prismatic cell interconnections, delivering the speed and precision needed to weld thousands of tab-to-busbar connections on multiple module and pack designs.
Our approach scales throughput while maintaining weld quality for EV batteries and energy storage systems. Laserax's automated laser welding solutions meet short cycle-time requirements while minimizing the heat-affected zone to protect battery integrity.
Laser processes are configurable for dissimilar metals (e.g., aluminum–copper) and can be adapted on the fly to varying thicknesses, geometries, and module designs. Remote, non-contact operation enables application-specific weld patterns that enhance joint strength and electrical conductivity.
✅ High-power, continuous-wave fiber lasers (up to 6 kW) for high-speed production
✅ Minimal HAZ with optimized heat input for robust mechanical properties
✅ Dissimilar metal welding without filler (Al–Cu, steel–Cu, etc.)
✅ On-the-fly parameter updates for changing designs and thicknesses
✅ Custom weld patterns for reliable bonds and low-resistance joints
From R&D to full-scale production, Laserax provides turnkey cells and services tailored to prismatic applications:
- a Battery Laser Welding Machine with dynamic clamping, integrated vision, weld monitoring, rework, contaminant management, and laser safety;
- a Battery Laser Welding Workstation for process development and small batches;
- and a Battery Laser Cleaning Machine to prepare tabs and busbars in-line.
Our experts support process definition, development, validation (shear/electrical resistance, penetration, aging, cross-section analysis), and ramp-up. HMI software provides weld monitoring feedback and manual control.
