Arc Pins

Non Thread Studs or Drawn Arc Pins are used in all types of applications. They can be welded to a flat surface, or to the inside or outside of an angle.

The Drawn Arc Stud welding is a process by which a metal fastener is welded to a base metal through a fusion weld. Using a ceramic ferrule to capture and retain the weld’s heat, the molten metal created by the process cools the weld site and produces a weld that is stronger than the stud itself. Drawn arc stud welding can be used with dissimilar metals such as mild and stainless steel, as well as aluminum and some specialty alloys. These studs can sometimes be referenced as NT Studs, NBL Studs or SWP Studs Studs, Weld Studs or Welding Studs.
