Information about arc stud welding

Pin-shaped metallic components with diameters up to approx. 25 mm are fastened on base sheets vertically by means of stud welding. Different procedure variants are available for the most diverse applications.

  • The stud welding procedures are generally characterised by high economic viability and good automatability.
  • The usable materials and material combinations are restricted in the case of arc stud welding. A wide variety of materials and material combinations can be joined using friction stud welding.
  • Applications can be found in all fields of the metal processing industry.

In the case of arc stud welding, an arc burns between the front face of the stud and the workpiece for a short time and partially melts the joining members (stud and sheet). After sufficient partial melting, the molten pools are connected with each other by the stud movement towards the sheet.

Depending on the procedure variant, the stud welding industry offers suitable power sources, movement jigs, studs and additional auxiliary materials (e.g. ceramic ferrules). The handling is comparatively simple but a large number of welding and boundary conditions must be coordinated in practice for successful and safe fabrication.


Our technical equipment

In our laboratory rooms, we have at our disposal stud welding installations for the drawn arc and initial contact procedures as well as for the friction stud welding of various designs and sizes.

In this respect, the performance range of the installations extends from thin pins (approx. 2 mm) to massive head studs (approx. 25 mm).

The field is looked after by three people (two engineers and one technologist).

  • Drawn arc stud welding (ceramic ferrule or shielding gas)
  • Initial contact stud welding (gap and contact variants)
  • SRM technology
  • Magnetically impelled arc sleeve or nut welding
  • Friction stud welding
  • Process monitoring with suitable testing devices
