THE MIDWEST FASTENERS
CAPACITOR DISCHARGE
(CD) STUD WELDING PROCESS
Capacitor Discharge (CD) Stud Welding involves the same basic principles and metallurgical aspects as any other arc welding procedure. When the MIDWEST FASTENERS stud gun is activated, a special precision Capacitor Discharge weld tip initiates a controlled electric arc from the studwelder capacitor bank which melts the end of the weld stud and a portion of the base metal. The weld stud is held in place as the molten metal solidifies instantly accomplishing a high quality fusion studweld.
Capacitor Discharge stud welding is generally used to weld smaller diameter studs to thin base metals, especially where reverse side marking is not permissible. Since the entire weld cycle is completed in milliseconds, stud welds can be made to thin material without pronounced distortion, burn-through or reverse side discoloration. As long as one end of stud is designed for Capacitor Discharge welding, CD studs can be manufactured in almost any shape. CD Stud Welding is compatible with just about any weldable material, and permits the studwelding of dissimilar metals.
