Capacitor Discharge Welding works based on the principle of discharging stored electrical energy from capacitors through the workpieces to create a weld. The capacitors store a high voltage charge, which is discharged through the weld zone, generating an intense current flow for a short duration. The equipment used in CDW typically includes:
Capacitor Discharge Welding (CDW) is a welding process that utilizes the discharge of electrical energy stored in capacitors to create a localized, high-intensity heat source for joining metal components.
A capacitor is used in welding to store electrical energy that can be rapidly discharged during the welding process. This discharge provides a high-intensity current flow, generating the heat required for melting the metal surfaces and forming a weld joint. What size are welding studs?
Capacitive discharge resistance welding uses large capacitors to store energy for quick release. Figure 1 shows a typical capacitor discharge curve. Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds.
Capacitive welders deliver repeatable welds even during line voltage fluctuations. Spot welding relies on the principle of metal resistivity to heat and fuse metal. A large current is passed through the work piece. Energy is dissipated due to the metal resistance in the form of heat which melts and fuses weld materials. There are two phases to
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.
