Fiber Laser Welding Assists Longer Battery Life for EVs
Fiber laser welding technology is contributing to lower cost and higher reliability batteries for the latest generation of electric vehicles. Fiber laser welding reliably produces consistently high-quality welds for electric vehicle batteries where aluminum, copper, nickel-coated steel and combinations of these materials are welded together. This article provides an update on the latest laser welding developments as they apply to these newest battery designs, including data to document the quality of laser welds of similar and dissimilar metal combinations. Automakers are reallocating and prioritizing their research and development budgets toward electrification of vehicles. By 2025, fewer than half the cars sold will be fully combustion-powered, as gas and diesel give way to hybrid, electric, and fuel-cell drivetrains. For this to occur, there will be significant investment to make electric vehicles more attractive and affordable for mainstream buyers. These investments will inc
