EV Battery Manufacturing
Handle battery manufacturing challenges with laser technology that offers higher yields and scalability.
- Reduce HAZ Weld the most sensitive materials with 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 Dissimilar Materials
Contacting dissimilar materials - like aluminum to copper - with excellent electrical conductivity, high mechanical strength, and precise control over penetration depth.
Copper Welding
Efficiently weld copper without process instabilities using the ARM fiber laser and achieve cost, reliability, and practical advantages over green lasers.
Weld Large Batteries
High-speed production Joining of large form factor cylindrical battery components with minimal heat affected zone, no spatter, and accurate penetration depth control.
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.
Foil Welding
Foil-to-tab welding with excellent weld penetration, minimal spatter, and reduced heat damage using single-mode ARM fiber lasers.
Battery Cooling Plate Welding
Weld large aluminum or polymer cooling plates in battery trays with high-speed and reliability.
Busbar Welding
Weld busbars with excellent control of workpiece heating, penetration depth, and weld width, whether it's steel, copper, aluminum, or a mixture of materials.
Busbar Stripping
CO2 lasers efficiently remove polymer insulating coatings at high speed
without damaging the underlying conductor.
Enclosure Welding
Filler-free ARM laser welding of aluminum battery modules and enclosures minimizes distortion, porosity, cracks and spatter.
Electrode and Separator Cutting
Cut coated battery electrodes (anodes/cathodes) and separator materials (including ceramics) with high precision and a small heat-affected zone.
Thin Film Electrolyte Sintering for next generation of solid-state Li-ion batteries
Excimer pulsed laser deposition of thin-film electrolyte layers for lithium-ion batteries delivers dense and stoichiometric films for improved storage and charging.

Teamtechnik: SmartWeld+ Fills the Gaps in Production Welding
When production automation experts teamtechnik were contracted to develop a production welding system, they looked to Coherent to supply the laser expertise. They ended up with a partner who helps them provide their customer with ongoing support.
"SmartWeld+ gives us great results and can readily adapt to make process changes. But the real reason we went with Coherent is their support. No other supplier was willing to do the development work necessary to ensure we could satisfy our end user’s requirements."
