Highly Productive Laser Welding of Battery Trays, Fuel Cells, Hair Pins, Cap-Can and Battery Contacts

Welding speeds are often the limit for the productivity of a laser welding station. Laser welding battery trays, particularly 6XXX alloys that require filler wire to prevent hot cracking, the welding speed can be increased by adding an oscillating function and using smaller spots with tactile welding optics. For other battery applications without additional wire, such as fuel cells, chillers, busbars, and hairpins, Scansonic has developed a new, very compact scanner device “Fast Component Welding Head”. This pre-focused, very precise scanner head with a fast Z-shifter enables oscillation or “jumps” at a frequency of up to 1 kHz. It is now possible to add and arrange multiple heads (and lasers) to suit the application within one laser station. This presentation explains the technology and shows application case studies.
