KCD Studwelding will launch its new CD66 capacitor discharge studwelder on stand 4102 during National Manufacturing Week 2007 at the Melbourne Exhibition & Convention Centre, from May 22 to 25.
The CD 66 capacitor discharge studwelder weighs 6.2 kg. Studwelder is a time saving tool where an arc welds the full cross-section of a weld stud to the base material in a fraction of a second.
KCD Studwelding designs, makes and sells its own welding systems and fasteners, specialising in the two types of studwelding namely drawn arc and capacitor discharge.
Drawn arc studwelding uses the energy from mains power via a DC power source. The energy used is lower current than that in capacitor discharge welding, but it has a much longer weld cycle, which creates a hot weld zone, making drawn arc studwelding suitable for fixing studs in structural situations. The stud diameters range from 6 mm to 25 mm.
Capacitor discharge studwelding uses energy stored in a bank of capacitors. This energy is discharged through a virtual short circuit creating a high current for a short period of time (6-milliseconds).
Capacitor discharge is commonly used with smaller diameter studs when welding to thin materials. The stud diameters can range from 3mm to 8mm. The stud materials are mild steel, stainless steel, aluminium and brass.
