Stud welding
Stud welding - technology
The drawn arc stud welding, short “stud welding” is a press-welding-technique. An arc is drawn between a stud and a workpiece, melting some of the metal on both parts. At the end of welding time the stud is plunged into the weld pool, the welding current is switched off and the weld pool solidifies.
Advantages of KÖCO-Stud Welding Technology
By means of KÖCO-Stud Welding Technology, Threaded Studs, plain studs, Tapped Studs, Shear Connectors, Anchoring Studs etc. of diameter 2-25 mm will be cross-sectionally welded onto sheet metal, pipes, profiles etc.
The advantages of KÖCO stud welding technology are obvious:
- A high degree of safety, thanks to cross-sectional joints
- High productivity through extremely short welding time
- Options for various combinations of materials
- Distortion reduced to a minimum through low thermal stress
- Very little or no damage to the reverse side
- Hollow parts remain leakproof
- Access to parts from one side only is sufficient
- Easy to operate for personnel trained on the job
- Conform to international standards: EN ISO 14555 and EN ISO 13918
- Shear connectors officially approved: European Technical Approval ETA-03/0039
- Innovative stud welding equipment and welding studs from in-house production
