Stud Welding is a quick and accurate method of attaching metallic studs onto metal surfaces. During the welding process, an arc is ignited between the face of a stud and the surface of the work piece. Once both surfaces melt, the stud is pressed against the work piece in a level manner and the two are attached.



Stud welding is increasingly used as a more efficient alternative to conventional hand welding techniques when attaching refractory anchors. The technique reduces installation times and eliminates the need for welding electrodes, thereby avoiding their associated toxic fumes and other challenges. Stud welding installations also require lower levels of expertise and reduced manpower thus significantly lowering costs. The following refractory anchors are stud welded:

· Gull Wing Stud Welded Anchors (G.W.S.W)

· Vee Wriggle Stud Welded Anchors (V.X.S.W)

· Vee Stud Welded Anchors (V.S.W)

· Vee Wriggle Drilled Base (V.X.D.B); Rotary Kiln Floating Anchors

· Corrugated Anchors (V.X.C)


In steel-concrete composite construction, shear connectors allow for the transfer of horizontal shear forces from the concrete slab to the supporting beams. As such, shear connectors are an essential part in the design and construction of steel-concrete composite structures.

Shear connectors are stud welded onto the steel skeleton structure of buildings and act as reinforcing components as it locks the support structure to the concrete floor. The use of shear connectors allows for composite construction to be done on a large scale.


Stud welding is also suitable for fastening ceramic fibre fixings that are used to support ceramic fibre linings across a range of operating temperatures. Ceramic fibre anchoring systems that can be attached using stud welding include:

· Press-On Clip Systems

· Fibre-lock Pins, Lock Washers

· Spring Clip Washers


Wear Studs are commonly applied on surfaces of earth moving machinery where excessive machinery wear is experienced. The systems ideally suited for use on ground engaging equipment in underground mines, open pit mines and general ore preparation plants. In the context of this application, high chromium and carbon wear studs are welded on the surfaces of machinery which is exposed to high abrasion thereby reducing wear and tear. This ultimately extends the service life of machinery and reduces maintenance costs.


Spike Studs on speed transport and guide rollers provide higher traction compared to conventional stud systems. In addition to supplying the highest traction, Spike Studs can be quickly and easily applied on-site, reducing downtime. Once installed, the systems prolong the life of rollers and can be rapidly maintained, resulting in more perpetual savings. Spike Studs have been successfully proven in the timber, paper and board products industries.

  1. Stud welding reduces component handling and is also suitable for thin plates, as well as components with limited or one-sided access.

  2. Resulting welds are leak and tamper proof.

  3. Since there is no need to punch holes in the parent sheet; common corrosion challenges are eliminated and workpieces are not weakened.

  4. Stud welding creates consistent welds that penetrate the surface of the material studs are attached to; resulting in weld joints which are stronger than the stud or parent material.

  5. The technique allows for various elements such as threaded studs, pins and tapped pads to be attached directly to metal surfaces.

  6. Eliminates preparatory practices like drilling, punching, threading, gluing, riveting, screwing or finishing thereby tremendously saving time and costs.

  7. Stud welding offers unmatched efficiencies.
