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.

ARC Stud Welding Process


  • 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

CD Stud Welding Method

  • 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.

CD Stud Welding Process


  • 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
