About Seller: Capacitor Discharge (CD) stud welding is a highly efficient technique for welding fasteners onto a wide range of metals such as mild steel, stainless steel, aluminum, brass, copper, and titanium. This process involves the use of a robust bank of capacitors to store energy at a specific voltage based on the size and material of the stud. When the welding process is initiated, this energy is discharged through a specialized "ignition tip" at the base of the stud, creating an immediate arc that melts both the stud base and the adjacent surface on the workpiece. Simultaneously, the welding gun drives the stud into the workpiece, creating a permanent bond as the melted material solidifies - all within 0.004 seconds.
Capacitor Discharge stud welding eliminates the need for drilling, tapping, punching, riveting, gluing, or screwing, making it particularly advantageous when working with thin gauge materials as it prevents marring or discoloration on the reverse side. This method is suitable for studs ranging in size from #4-40 (M3) to 3/8-16 (M10). Standard handgun models are available off the shelf to meet regular applications, while custom-designed automated production systems are offered for high-volume projects. Additionally, a comprehensive selection of standard U.S. and metric studs in mild steel, stainless steel, and aluminum is available in stock, with non-standard stud designs and alloys available upon request.
