Stud welding general information

The 12 most important questions and answers

1. What is stud welding?

  • Threaded studs, pins, tapped pads, clips etc. are welded by an arc without additional material.

2. How does stud welding work?

  • An arc is ignited between the face of the stud and the surface of work piece; once both parts are melted, the stud is smoothly pressed against the work piece and then joined together.

3. What kind of processes are available?

  • Capacitor discharge stud welding with tip ignition (TS) according to DIN1). Especially suited for welding on thin plates from about 0.5 mm minimum; plate thickness: 1/10 of stud diameter. Welding range: M3 to M8 (M10)
  • Drawn arc stud welding (DS) according to DIN1), process variations:
    drawn arc stud welding with ceramic ferrule or shielding gas; short cycle drawn arc stud welding; capacitor discharge drawn arc stud welding. Especially suited for welding on thicker plates of 2 mm and above. Minimum plate thickness: 1/8 of stud diameter. Welding range: dia. 2 to 25 mm (M24)

4. Where is stud welding used?

  • Capacitor discharge stud welding: sheet metalwork, electronic industries, switchboard cabinets, laboratory and medical equipment, food industry, household appliances, communications engineering, vending machines, windows, glass constructions, insulation technology, industrial kitchens etc.
  • Drawn arc stud welding: steel construction, mechanical engineering, shipbuilding, structural and civil engineering, power plants and combustion systems, boiler and plant equipment, insulation and windows, buildings.

5. How strong is the joint?

  • Because the stud is joined with the work piece over the whole surface of the stud, the strength of the joint is even higher than the base material or the stud.

6. Which materials are weldable?

     Generally materials of the same kind should be welded*

  • Capacitor discharge stud welding according to DIN1) 2): steel (mild and alloyed steel), aluminum, brass
  • Drawn arc stud welding according to DIN1) 2): steel (mild and alloyed steel), aluminum

7. Which stud diameter and stud length can be welded?

  • Capacitor discharge stud welding according to DIN2): M3 to M8 (M10), dia. 2 to 10 mm
  • Drawn arc stud welding according to DIN2): dia. 2 to 25 mm (M24)

8. Which stud shapes are available?

  • Capacitor discharge stud welding according to DIN2): threaded studs, pins, tapped pads, christmas tree studs, paint clearing studs, grounding clips, cupped head pins, insulation pins.
  • Drawn arc stud welding according to DIN2): threaded studs, pins, tapped pads, christmas tree studs, concrete anchors, collar studs, insulation pins.

9. How long does the welding process last?

  • Capacitor discharge stud welding: 1 to 3 msec
  • Drawn arc stud welding: 5 msec to 1.5 sec

10. Which quality of the plate surface is required?

  • The surface of the plate must be electrically conductive.
  • Varnish, aluminium layers, scale, rust and plastic surfaces are to be removed. Check galvanized and oily plates for their weldability.
