CD stud welders – or a capacitor discharge stud welder – are used frequently to weld small metal studs to thin work pieces. But what is it about capacitor discharge welder systems that makes them so popular? The experts on stud welding are here to explain!

Capacitor Discharge Stud Welding: The Welding Process

A capacitor discharge welder comes with both a power unit and a CD weld gun. A CD stud welder is a specific kind of stud welding system that uses capacitors to store energy for quick release. Energy in the form of heat is dissipated by an electrode through the stud and work piece, fusing the weld materials. This process only takes a few milliseconds, leaving a strong weld in no time.

What are the Benefits of a Capacitor Discharge Stud Welding?

A capacitor discharge welder creates strong quick welds because it releases energy extremely quickly and with large peak currents. Furthermore, the way the unit is designed allows for more energy to go directly into the weld formation, as opposed to the surrounding material. Therefore, the portion that is distorted by the weld is limited to a very small area around the weld spot, leaving us with a clean weld. This is excellent for aesthetic reasons.

One of the most important benefits of capacitor discharge welding is the ability for back-to-back repeated welds. Since energy is stored before use, a capacitor discharge spot welder can deliver a continuous stream of welds, even when line voltage fluctuates.
