CD Weld studs are installed using the "capacitor discharge" stud welding method which does not require ceramic ferrules or gas. CD studs diameter range from 4-40 thru 3/8 and are manufactured from low carbon steel , aisi 1006-1020; stainless steel, 300 series, copper alloy 260 and 268 aluminum alloy 1100, 5000 and 6061 series. For base- metal thickness under 0.062 in (1.6 mm) the capacitor discharge stud should be used. The base metal can be as thin as 0.020 in. (0.5 mm) without melt through occurring. CD Studs are designed with a tip or projection on the weld end. Weld Base can be flanged or non- flanged.
