As electric mobility, renewable energy, and portable electronics expand rapidly, the demand for high-performance battery packs continues to grow. A key factor in battery reliability is how cells are connected into modules. Laser welding has emerged as the go-to method for precision, speed, and performance, and RMA is leading this transition with advanced laser automation solutions.
Modern battery production needs to be efficient and precise. Whether joining aluminium tabs, copper busbars, or battery enclosures, laser welding provides a clean, non-contact, high-speed alternative that reduces thermal distortion and enables welding of dissimilar metals.
Welds in < 0.1 seconds. Machines like RMA Battery Welder Max are built for high-volume production with automation and real-time QC.
High beam focus = accurate, spatter-free welds with minimal thermal impact.
Laser welds create strong, conductive joints suitable for high-current EV batteries.
All models run on the intuitive BW Interface software for weld configuration and traceability.
RMA supports clients through its Laser Application Center (LAC), offering full-cycle support—from prototyping to ramp-up. Expertise in fixture design, monitoring, and validation ensure production-ready processes.
