Stud Welding Process

Arc Stud Welding Method

  1. Stud and ceramic ferrule are placed in gun and pressed against work surface.
  2. The arc is drawn when the trigger is pressed, which melts the fluxed end of the stud along with the immediate work area.
  3. 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.
  4. 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 ¼”
  • 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

CD Stud Welding Method

  1. Stud is placed in weld gun and pressed against work surface.
  2. 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.
  3. The arc melts the entire face of the stud along with the parent material, and the stud is forced into the molten metal.
  4. Metal solidifies and weld is completed in milliseconds.


  • No drilling or tapping
  • No cleanup
  • Will not vibrate lose
  • No weld fillet
  • Reverse side can paint finished before welding
  • Parent base materials from .025” and up
  • Very fast, 5-6 milliseconds
  • Weld up to 20 studs per minute
