CD Studs Metric and Imperial Stainless steel mild steel aluminum

CD Studs Overview

CD Studs come in small diameters (up to 3/8”) and can be made out of mild steel, stainless steel or aluminum. They are used in a wide range of industrial manufacturing applications. And unlike arc studs, CD studs do not leave a mark on the reverse side of the welded surface – an important distinction when aesthetics are at play.

CD Stud Welding Process

Step 1: The stud is loaded in to the gun and placed up against the metal welding surface.

Step 2: After the gun is activated, a capacitor discharges a high energy current through the bolt which melts both the stud and the surface of the base.

Step 3: The gun then pushes tne stud in to the molten metal.

Step 4: The molten steel then cools quickly, creating a strong weld between the stud and the base material. This process happens in milliseconds.
