What is Capacitor Discharge (C.D)Projection Welding?
Projection welding is a modification of spot welding. In this process, the weld is localized by means of raised sections, or projections, on one or both of the

Capacitor Discharge Welding Process:
Capacitor Discharge (CD) stud welding is an extremely efficient method of welding fasteners to a wide variety of metals like:
- Mild steel
- Stainless steel
- Aluminum etc..
The process utilizes a powerful bank of capacitors to store energy at a specific voltage determined by stud size and material. When a weld is initiated, this energy is "discharged" through a special "ignition tip" at the base of the stud, creating an instantaneous arc which melts both the base of the stud and the adjoining surface on the work piece. At the same time, the welding gun forces the stud into the work piece, resulting in a permanent bond as the molten material solidifies all in 0.004 seconds
Capacitor Discharge stud welding eliminates drilling, tapping, punching, riveting, gluing, and screwing; and is especially beneficial when working with thin gauge materials due to the absence of reverse-side marring or discoloration.
