The Stud Welding Process: Capacitor Discharge

Sunbelt Stud Welding

CD stud welding is specifically used for fastening small diameter studs (1/4″ and under) to extremely thin parent metals. As indicated by its name, this stud welding system uses energy stored by a capacitor to complete its welds. When the trigger is pulled, energy is instantaneously discharged through a special timing tip. Once the tip of the fastener is melted, the stud is forced into the molten metal. The metal then solidifies, leaving a neat but sturdy weld all in a matter of milliseconds.

The extremely weld cycle allows for operators to perform several welds back to back. Moreover, the brief weld cycle also means that fasteners can be welded onto thin sheets without pronounced distortions in the metal. Dissimilar metals can also be welded with the CD stud welding process.

While the process itself seems easy, training and experience is required to create quality welds. A deficit or excess of power and spring forces can produce a weak weld. Moreover, one need to have basic knowledge about the magnetic qualities of different types of metal to properly weld.
