New Capacitive Discharge Welding Process Enables In-process Monitoring for Battery Pack Joining
While ultrasonic and laser welding are both effective methods for battery foil welding, neither can be monitored in process. So when a battery batch is defective, the problem is not identified until after material, time, and money as been spent.
EWI recently tested a resistance spot welding technique that uses a capacitive discharge power supply for battery welding. The system has the capacity to collect and measure data in process, thus offering the potential to monitor quality in real time, and ultimately reduce costs and waste.
