Stud Welding Explained
Better, Faster & Lower Cost .....
There are two basic stud welding processes, Capacitor Discharge (CD) and Drawn Arc (ARC).
The two basic stud welding processes are based on the same basic principles and metallurgical aspects involved in all other arc welding processes, in that a precisely controlled electric arc is used to melt the end of the stud (electrode) and a small area of the base metal. The stud is plunged into the molten weld pool automatically, producing a dense, high quality, full cross section fusion weld that is stronger than the stud itself.
The welding is fast. The weld cycle is measured in milliseconds for the CD process and microseconds for the ARC process.
Studs can be welded to material as thin as .015" with CD. There is no limit to the ultimate thickness of the base material. Weld stud diameters range from 10 Gauge to 1 1/4".
Stud welding is applicable to mild steel, stainless steel and Aluminum.
Welded fasteners or studs may be almost any size, shape or type and there is literally hundreds, however, they must be made of weldable material and one end of the fastener must be designed for welding.
