The voltage on caps is measured using the adc4 port, with the voltage divider made by resistors rvr2a and rvr2b. Capacitor discharge stud welding capacitor discharge cd stud welding is generally used to weld smaller diameter fasteners to thin base metals. A 1 farad capacitor will work for pack building but for hotter and more consistent. Capacitor discharge cd welding has become a valuable technique for study ing methods of joining parts made from rapidly solidified materials. Capacitor discharge resistance welding capacitor discharge resistance welding is a special form of resistance projection welding in which the welding energy is provided by the release of energy stored from a large capacitor bank.
Designed for highprecision, mass production, high capacitive discharge resistance welding solutions are available from t. Capacitor discharge studs available flanged and nonflanged are used with thin materials to eliminate discoloration and marring to the reverse side of the material. Just a raw, simple, single shot cd welder to allow me to build a few battery packs. Technology classification and functionality applications from small to large welding parts good and less parameters finding and monitoring welding quality get and save welding jigs supporting the quality.
Capacitor discharge welding uses short weld cycles and are commonly used for mild steel, stainless steel and aluminum applications. All pins are compatible and recommended for use with all brands of cd stud welding equipment. The discharge works in a similar way, bringing high the pin pd6, that opens the q5 mosfet, that dumps the capacitor energy into the r power resistor. Preparation of pieces the pieces are to be prepared in such a way that one piece has a projection and both pieces provide sufficient contact for the welding electrodes.
