Capacitor Discharge Stud Welding Process

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.

Drawn Arc Stud Welding Process

Drawn-arc stud welding is an extremely efficient method of attaching fasteners primarily to mild steel and stainless steel by utilizing a constant-current DC power supply, typically a 3-phase transformer-rectifier, equipped with integral controls to operate a special drawn-arc stud welding gun.
