Capacitor Discharge Stud 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
- brass
- copper
- titanium
The Power of Capacitors
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!The Advantages of CD Stud Welding
Capacitor Discharge stud welding offers a host of advantages including:- Eliminating the need for drilling, tapping, punching, riveting, gluing, or screwing
- Especially beneficial for thin gauge materials due to the absence of reverse-side marring or discoloration
- Suitable for studs ranging in size from #4-40 (M3) thru 3/8-16 (M10)
