Stud welding

Stud welding

Stud welding is extremely useful for making thin sheet metal quick and easy to assemble, without having to drill through the material. This in contrast to a classic bolt/nut connection. Where in the past bolts and internally threaded bushes were welded manually, Raytech now has a stud welding machine.



Stud welding is the connection of studs or bolts to a substrate using a gun. An electric arc is ignited between the substrate and the post, melting the surface of the post and the substrate. As a result, they become one.

Raytech uses ‘capacitor stud welding’, where the arc is generated by the discharge of a capacitor. There is an ignition tip on the underside of the bolt, on which the arc ignites, melting both the tip and the bottom of the bolt.

Pins and bolts are placed manually at Raytech. This means high flexibility and extremely short start-up times compared to automatic stud welding.

Stud welding can be used for bolts M2 to M10. min. sheet thickness depending on the shape of the part. Different types of materials can be processed, including steel, stainless steel, aluminum and brass.


Different types of pins: threaded bolts, coarse threaded bolts, internally threaded bushes or simple pins, flat plugs and insulation nails. Before welding, paint, rust or deposits must be removed so that the surface is conductive.



  • Versatile, connect dissimilar materials
  • Fastening without having to drill through the plate (classic bolt-nut connection)
  • High processing speed: manually up to 8 pens per minute
  • Very local heating, which allows for welding on thin plate without deformation (small HAZ, Heat Affected Zone)
