Capacitor discharge welding is mainly used for projection welding recently. By default, capacity discharge is a single-pulse method [2, 14, 17,18,19,20,21]. It is very difficult to influence the discharge time of the capacitor. Only welding force and the loading energy can be set. The new innovative multi-pulse technology, which is described

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.
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.
The results presented here indicate that electrolytic capacitors, configured to provide similar charge voltage and energy storage, can yield identical weld performance results. Process, mechanical strength, and metallographic results are all identical for the two capacitor arrangements.
Surface activation could be observed in high-speed images of past investigations, which can be explained by metal vaporization [7, 8]. The aim of this publication is to use experimental and simulative investigations to describe the bonding mechanism in projection welding by capacitor discharge.
