Size and thickness limitations of workpieces: Capacitor Discharge Welding is best suited for small-scale applications and workpieces of relatively small size and thickness. The equipment and process may have limitations when it comes to welding large or thick materials, as the heat generated may not be sufficient for effective bonding.
Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material. The heat affected zone, where the properties of the metal have been changed from rapid heating and cooling, is localized to a small area around the weld spot.
