Stud Welding Process

Arc Stud Welding Method

Stud and ceramic ferrule are placed in gun and pressed against work plate.
The arc is drawn when the trigger is pressed which melts the fluxed end of the stud along with the immediate work area.
The ceramic ferrule shields the arc concentrating the heat, the gun then forces the stud into the molten pool of metal integrating it with the work plate.
The metal solidifies and welder breaks away the ceramic ferrule to expose the weld fillet around the base of the stud.

Almost any size or type of stud can be welded
With the Arc process, you obtain a full fusion weld that becomes stronger than the stud itself
Diameters up to 1-1/4”
Labor costs are dramatically reduced with the process because through-hole preparation is eliminated and the weld can be completed by a single worker
Penetration of weld zone for structural-type strength
No holes to drill

Stud is place in weld gun and pressed against work
Ignition of the arc is started when stored energy is discharged when trigger is pulled through a special weld “timing” tip and stud starts downward.
The arc melts the entire face of the stud along with the parent material and the stud is forced into the molten metal.
Metal solidifies and weld is completed in milliseconds.
