Why Stud Welding

Stud welding is the welding of elements like threaded studs, pins, tapped pads etc by an arc without additional material.


It works when an arc is ignited between the face of the stud and the surface of the work piece. Once both parts are melted, the stud is smoothly pressed agains the work piece and then joined together.


There are two main processes utilised with stud welding:


  1. Capacitor discharge stud welding - this is especially suited for welding on thin plates from about 0.5 mm. Ideal applications for CD Stud Welding include 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.
  2. Drawn arc stud welding - especially suited for welding on thicker plates of 2mm and above. Ideal applications for Arc Stud Welding include steel construction, mechanical engineering, shipbuilding, structural and civil engineering, power plants and combustion systems, boiler and plant equipment, insulation and window construction. Drawn arc stud welding can be performed with a number of variations including drawn arc stud welding with ceramic ferrule or shielding gas, short cycle drawn arc stud welding and capacitor discharge drawn arc welding.
