Automotive Battery Welding

Handle automotive battery welding challenges with fiber laser technology that offers higher yields and scalability.

  • Reduce HAZ Weld the most sensitive materials with ARM lasers that minimize part heating.
  • Drive Quality Lower weld porosity and spatter, and increase precision and repeatability.
  • Increase Throughput Cut cycle time, plus eliminate rework and postprocessing to improve productivity.

Welding Demanding Materials

Efficiently weld copper, aluminum, or dissimilar materials without process instabilities using the ARM laser and achieve cost, reliability, and practical advantages over green lasers.

Foil Welding

Foil-to-tab welding of pouch-type battery cells with excellent weld penetration, minimal spatter, and reduced heat damage using the single-mode ARM lasers.

Can/Cap Welding

High-speed, hermetically-sealed welds for prismatic cell battery can/caps, housings, contacts, and safety valves with low spatter, cracking, and porosity.

Busbar Welding

Weld aluminum foils to copper busbars with excellent electrical, thermal and mechanical properties utilizing the power and spatial control offered by the ARM laser.
