Copper Coated Capacitor Discharge PT Studs

Cd-studs

Cd studs are also known as capacitor discharge studs, generally speaking, is the diameter of M3-M10, length within 80 will have a large number of spot, spot material is mainly copper-plated, stainless steel, aluminum material. If you need other materials can also be customized production. Cd studs standard is EN ISO13918.

The principle of Cd studs welding is that the equipment will firstly charge the pre-set energy amount into the capacitor, and then when welding, the energy is released from the capacitor all at once for welding, and the welding time is 1-3 milliseconds. Since the energy is not constantly available, the welding capacity of stored energy stud welding is limited and is generally used to weld studs with a diameter of 3-10 mm Cd studs.

Cd studs In thin plate welding:

1. the weld results of stored energy stud welding fully meet the requirements;

2. the welding effect of stored-energy stud welding is better than that of drawn-arc stud welding.

Plate specification: 304 stainless steel plate with a thickness of 2mm.

Stud specification: M8 stainless steel stud （Cd studs）

Discharge stud welding: the minimum requirement for plate thickness is 1/10 of the diameter of the stud. below is M4 weld studs on workpiece
