Welding

SHARE
Connecting cells to each other or adding solder tabs or other circuitry to cells is an important step in battery assembly. Soldering directly to cells is not acceptable as the integrity of the cell will be destroyed by the heat. Connections are made using either precision capacitor discharge welders or three-phase high-frequency welders. During welding operations weld strength is verified using a non-destructive pull tester.
