Process:

Capacitor Discharge Stud Welding:
+ Welding energy is obtained from banks of capacitors which is charged to the voltage selected for the particular application.
+ This energy is discharged through the stud projection / tip, giving a high density current which disintegrates the small projection / tip on the base of the stud
+ This leaves an ionised gap between stud and work piece across which the welding current continues to flow in the form of an arc
+ Pressure from the return spring in the welding tool forces the stud onto the work piece, completing the weld in a split-second
+ The capacitor discharge stud welding system operates on a single-phase 50Hz A.C. Mains supply at 220/240 volts.

Arc Stud Welding (SW): -
+ The stud is loaded into a stud welding gun, the ferrule / arc shield is placed in position over the end of the stud, and the gun is properly positioned over the work piece.
+ The trigger is then depressed, starting the automatic welding cycle
+ A solenoid coil within the body of the gun is energized
+ This lifts the stud off the work piece and, at the same time, creates an arc
+ The end of the stud and the work piece are melted by the arc
+ When the preset arc period is completed, the welding current is automatically shut off and the solenoid de-energized by the control unit
+ The mainspring of the gun plunges into the molten pool on the work to complete the weld
+ The gun is then lifted from the stud and the ferrule is broken off
+ The arc stud welding system operates on a 3-phase 50Hz A.C. mains supply at 440 volts using a DC power source with high open circuit voltage.
