ARC WELD STUDS: ANNULAR RING (NAVY) ARC FASTENERS

The Annular Ring Arc Stud, or navy stud, is a ringed weld stud for application with arc stud welding equipment. This type of stud welded fastener is usually pointed on the weld end for studwelding applications. Available in low carbon steel, stainless steel and Aluminum, other special materials and grades are available. The annular ring stud style is characterized by a base area without threading and external rings starting above the unthreaded portion. Studwelding of the weld stud burns off a portion of the base so that the pre-weld, post-weld length dimension should be considered. All orders for arc weld studs from Midwest Fasteners include ceramic studwelding ferrules properly sized for the weld stud ordered. Special retainers known as annular ring caps, or "mushroom" caps, are used with the annular groove weld stud.
