Arc Weld Studs are installed using the "arc stud welding" process, where a ceramic ferrule or gas is required to form weld fillet.
Arc studs are manufactured from low carbon steel, aisi 1006-1020, 300 series stainless steel, and 5000 series aluminum. Low carbon steels can be arc stud welded with no metallurgical problems. The upper limit is 0.03 %. Stud welding of steel which exceeds 0.03 % carbon must be evaluated.
If medium and high carbon steels are to be stud welded, preheat must be used to prevent cracking in the heat affected zones. Most important factor regarding work section is that material must be heavy (thick) enough to permit welding the studs without melting through.
Arc studs are available in various shapes and forms. Diameters ranging from 1/8 in. (3.2 mm) through 1 ¼ in (31.8 mm) and lengths as required. Arc studs are manufactured with an arc stabilizing and deoxidizing flux.
