Energy storage welding, also known as Capacitive Discharge Welding (CD Welding), involves the use of a power supply that extracts energy from the power line and stores it in welding capacitors1. It is commonly used for welding studs with smaller diameters, where stored energy is released from a capacitor at the moment the stud contacts the base material, causing them to melt and weld together2.

The Department of Energy’s (DOE’s) Vehicle Technologies Office estimates the cost of an electric vehicle lithium-ion battery pack declined 89% between 2008 and 2022 (using 2022 constant dollars). The 2022 estimate is $153/kWh on a usable-energy basis for production at scale of at least 100,000 units per year. That compares to $1,355/kWh in 2008.

A form of resistance welding in which the electrical energy needed to cause Joule heating in the workpieces is obtained from a bank of capacitors or condensers. These machines draw power from the supply line over a relatively long time between welds, accumulating power to deliver to the electrodes during a short weld time.
