Weld studs and fasteners for capacitor discharge (CD) and drawn arc (DA) stud welding processes.

Weld studs are generally used in composite floor decks, which are welded to steel beams for shear resistance, or used in composite beams to make the performance of composite floor decks more efficient. Used in the metal floor deck, the general studs need to weld the metal floor deck and the steel beam into one. The diameter of Weld studs is 13 mm, 16 mm, 19 mm, 22 mm, generally 16 mm and 19 mm for metal floor deck. The length of Weld studs is determined according to the thickness of composite slab and the height of metal floor deck.
