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?
Capacitive discharge welding, particularly for large-scale systems, is typically done using film-type capacitors. These capacitors store energy along alternating plates separated by a dielectric film. Charge is stored statically along the lengths of the plates. The basic configuration of the film capacitor is provided in Figure 1.
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.
Size and thickness limitations of workpieces: Capacitor Discharge Welding is best suited for small-scale applications and workpieces of relatively small size and thickness. The equipment and process may have limitations when it comes to welding large or thick materials, as the heat generated may not be sufficient for effective bonding.
Capacitive discharge or CD welding is a variant of resistance welding(1,2). The process differs from the conventional variants largely in the type of power supply used. Conventional systems provide some variant of alternating current to a transformer arrangement.
Similar results for the welds made using the E-cap array with the 213:1 turns-ratio are provided in Figure 15. Comparative metallographic data from welds made using the film capacitor(3) are provided in Figure 16. The micro-structural response from welds made with the two capacitor types is again nearly identical.
