Aluminum Threaded Capacitor Discharge Weld Studs are used in all types of applications. They can be welded to a flat surface and are especially useful when reverse side marking is a concern.  Most Capacitor Discharge applications involve thinner gauge material with a ¼” thickness or less.  The Capacitor Discharge Stud welding is a process by which a metal fastener is welded to a base metal through a face weld. CD Stud Welding can be used with dissimilar metals such as mild and stainless steel, brass as well as aluminum and some specialty alloys.  These studs can sometimes be referenced as CD Studs, ATA Studs, ATC Studs or ATS Studs. Weld Studs or Welding Studs.
