The Production;:
The CD Welding Studs are made by Cold Forming / Truning/Lathing Technical.
1.For Flanged Studs, By Cold Forming Technical.(Making the Flange an the Welding Point )
2. For Non-Flanged Studs, Cold Forming 1st making the "Weld Point" and "Flanges", then Turning/Lathing CNC to cut off the Flanges. Or use directly Turning/Lathing to make the Weld Point. and then Threaded.
The Process;
1. Stud against the work plate
2. Stored energy discharged through special weld "timing" tip; stud starts downward
3. Stud forced into molten metal
4. Metal solidifies; weld is completed in a split secon

Capacitor Discharge (CD) Stud Welding
Advantages of CD
1.Welding to thin and sheet metal grade material
2.No reverse side marking
3.Up to 3/8" diameter fasteners
4.Only 115 volt power required
5.Up to 20 welds per minute
6.Welded metal fastening of dissimilar metals
Weldability; (More info. pls see ISO 14555.)
Only weldable materials shall be used for studs.
Non-alloyed steel studs are weldable if the hardness in crease is low. In general this is the case when the carbon content is
≤0.20%.Fee-cutting steel studs are generally not weldable.Killed materials shall be used.
Austenitic Stainless steel studs are generally weldable.Fee-cutting steel studs are generally not weldable.
Durability;
The durability of studs is dependent on their use and environmental exposure to which they are subject.
The mechanical durability of studs is assured for a reasonable economic working life if the studs comply with
the requriements of this International Standard 13918.
