Bend test with hammer or with pipe, making the welding stud bent 30 degree, there are no visible cracks on the welding area and the heat-affected zone in the weld stud and shear connector.

  Arc studs range from a #8 to 1 1/4" diameter. The lengths are variable from 3/8" to 60" (for deformed bars). Arc studs are typically loaded with an aluminum flux ball on the weld end which aids in the welding process.

Sanmen Nuclear Power Engineering


Stud welding is a process for joining a metal stud to a work piece. Stud welding guns hold the stud in place above the material to which it is to be joined. Electrical energy is used to heat the interface of the stud and the parent metal. The stud is then plunged into the parent metal to join them. This process uses a ceramic arc shield called a ferrule. The ferrule surrounds the stud to keep the molten metal contained and shield the arc.

Since arc stud welding time cycles are so short, heat input to the base metal is very small compared to the conventional arc welding. Because there is such a low heat input, the heat-affected zones (HAZ) are very small and minimal distortion occurs in the base metal where the  stud is located.

Differences Between Capacitor Discharge Welding and Drawn Arc stud Welding

1.Arc Stud Welding (with ceramic ferrule)Stud welding with ceramic ferrule, inert gas stud welding, short cycle stud welding.  The drawn arc stud welding method allows welding of studs 1/8" to 1 1/4" diameter made of non-alloyed, alloyed, stainles and heat-resistant steels to suitable base materials.

Stud fastener 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.A ceramic arc shield concentrates the heat and retains the molten material in the weld area from maximum weld strength and reliabillity.At the precise moment the fastener and the parent metal become molten, the fastener is automatically plunged into the work surface. The metal solidifies and a high quality fusion weld is completed.The metal solidifies and welder breaks away the ceramic ferrule to expose the weld fillet around the base of the stud.

2.Capacitor Discharge Stud Welding (CD stud welding)  This process is suitable for welding 12 gauge through 5/16" diameter studs made of non-alloyed and stainless steel, aluminum and brass

Stud is place in weld gun and pressed against workThe weld gun is activated and stored energy is discharged through the fastener melting the full diameter of its base and protion of the parent material.Spring-loading forces the fastener into the molten metal.Metal solidifies and weld is completed in milliseconds.

Advantages for Arc Stud Welding

high reliability thanks to deep penetration and precisely calibrated weld filletAlmost any size or type of stud can be weldedPenetration of weld zone for structural-type strength Larger Diameters up to 1-1/4”No need through-hole preparation,the weld just by a single worker,Labor costs are reduced Welded metal fastening to heavier base materials

Advantages of CD Stud Welding Method

Welding to thin and sheet metal grade materialNo reverse side markingUp to 3/8" diameter fastenersOnly 115 volt power requiredUp to 20 welds per minuteWelded metal fastening of dissimilar metals Very fast, 5-6 millisecondsWill not vibrate loseNo drilling or tapping


Designed for lightness and balance.Comfortable to use, minimises operator fatigue.Made from impact resistant, high strength Verton.Accessories – various accessories and attachments are available to solve specific problems.Extensions are available for both hand tool and earth cables.
