The design and construction of larger form factor cylindrical batteries for electric vehicles requires a number of welding processes, and these vary by manufacturer and design. But the most challenging and sensitive ones all share certain common requirements like minimal HAZ, accurate penetration depth control, minimal spatter and high process speed (typically somewhere in the 200 – 500 mm/sec range). Plus, some important battery joining processes also require welding of dissimilar metals.
Coherent has developed the Adjustable Ring Mode (ARM) technology to address all these requirements. The ARM laser beam consists of a central spot surrounded by another concentric ring
