Arc Stud Welding

Arc Stud Welding involves the same basic principles and metallurgical aspects as any other arc welding procedure, in that a controlled electric arc is used to melt the stud or electrode and a portion of the base metal. The stud is thrust automatically into the molten metal and a high quality fusion weld is accomplished where the weld is stronger than the stud itself. Stud Welding is applicable to mild steel, stainless and aluminum.

ARC stud welding is generally used to weld larger diameter studs to thick base metals. ARC studs may be almost any shape, however, they must have one end of the stud designed for ARC welding and must be made of weldable materials. Mild steel, stainless steel, and aluminum are applicable materials for ARC stud welding.

Welded fasteners or studs may be almost any size or type and there are literally hundreds, however, they must be made of weldable materials and one end of the fastener must be designed for welding. Conventional DC welding machines of all types may be used, but special power units designed specifically for stud welding are also available.
