A capacitor is used in welding to store electrical energy that can be rapidly discharged during the welding process. This discharge provides a high-intensity current flow, generating the heat required for melting the metal surfaces and forming a weld joint. What size are welding studs?
Capacitor Discharge stud welding is a process that eliminates the need for drilling, tapping, punching, riveting, gluing, and screwing. It is especially beneficial for working with thin gauge materials due to the absence of reverse-side marring or discoloration. This process is suitable for studs ranging in size from #4-40 (M3) thru 3/8-16 (M10).
Capacitor Discharge Welding (CDW) is a welding process that utilizes the discharge of electrical energy stored in capacitors to create a localized, high-intensity heat source for joining metal components.
Even though capacitor discharge welding (KE welding) is often still considered somewhat exotic among the welding technologies, the fact is that it can generate high welding currents in an extremely short time. And that is why it is often first choice for process-reliably solving welding job problems.
Electrolytic capacitors (E-caps) offer a potential alternative for large capacity CD welding systems. E-caps incorporate an electrolyte impregnated into a separator. The separator is then sandwiched between anodic and cathodic foils. A dielectric is also used to prevent direct contact of the foils with the electrolyte.
Capacitor Discharge Welding works based on the principle of discharging stored electrical energy from capacitors through the workpieces to create a weld. The capacitors store a high voltage charge, which is discharged through the weld zone, generating an intense current flow for a short duration. The equipment used in CDW typically includes:
