Threaded Stud
Capacitor discharge stud welding has been successfully used for many years all over the world. It allows weld studs with a maximum diameter of M12 to be welded. The welding process is executed by discharging the capacitor battery within a fraction of a second from 1 – 3 ms (0.001 – 0.003 sec.) using the welding element’s ignition tip.
This procedure has proven invaluable especially in vehicle construction, sheet metal forming and decorative metal design.

| The materia lspecifications conform with DIN EN ISO 13918 and DIN EN ISO 14555.Forwelding studs from other materials please send us you rinquiry or contact us. On demand, the material properties can be verified by an inspection document (test report,inspection certificate) according to DIN EN 10204. We are pleased to inform you about weldability to different base materials and welding parameters.
Welding pip Welding studs for capacitor discharge stud welding have a cold formed calibrated welding pip with length and diameter tolerances closely controlled. At the welding pip the welding process is initiated and it determines the length of the welding time.Therefore exact dimensions of the welding pip are decisive for proper welding results.
