Capacitor Discharge (CD) Stud Welding

Capacitor Discharge (CD) Stud Welding is a semi-automatic arc welding process. Small diameter fasteners (1/4″ and under) are end welded to extremely thin gauge parent metal. The CD process operates on the principle of capacitor stored energy. The equipment system instantaneously discharges through a special weld “timing” tip. The entire weld cycle completes in several milliseconds. Welds can be made to thin sheet without pronounced distortion, burn-through or discoloration. CD welding can use dissimilar metals.
