What is Capacitor Discharge Welding (CD welding)?

Capacitor Discharge Welding (CD welding) is a fast form of resistance welding that utilizes capacitors to deliver power to the part. Capacitors are charged with large amounts of energy, which is then rapidly released into the parts within milliseconds.

Why is a capacitor used in welding?

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?

What is a capacitive welder?

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
