Capacitive Discharge Welding
Capacitive Discharge Welding (CDW) is a similar process to RSW except large amount of energy is released in relatively a short amount of time. A research group at The Ohio State University working under supervision of Dr. Menachem Kimchi and Jerry Gould from EWI has investigated the feasibility of Al/Steel joining via this process. Figure 1 ...

Resistance and Percussive Arc Welding in Diodes, Capacitors, …
Low-voltage capacitors that have high capacitance commonly are used in power supplies for capacitor-discharge percussive welding. The capacitor is charged by direct current from a rectifier or generator, and the welding energy is stored at 50 to 300 VDC and later discharged to make the weld.
Keeping a Lid on Capacitor Heat: Enhancing Performance and …
When they applied an electric field of 10.8 MV/m, the capacitors underwent an adiabatic temperature rise (and fall) of 2.5 degrees C per cycle at room temperature. With the cold sink steadily cooling over the course of about 100 cycles, its temperature dropped by up 5.2 degrees C compared with the hot sink.

Capacitor discharge welding primarily applies to projection welding. Components with ring projections up to 200 mm diameter can be welded with peak …
What is Capacitor Discharge Welding?
Capacitor Discharge Welding 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. It …
Annealing Process of Steel
As understood from the above figure, in the full annealing process, steel is heated above the upper critical temperature (A 3) and then cooled very slowly the case of partial annealing, steel is heated to a temperature that lies between lower (A 1) and upper (A 3 or A cm) critical temperature and then cooled slowly. ...
Hermetically sealed SMD tantalum capacitors
walls after the capacitor element is positioned within the ceramic housing. The lid is typically made of metal materials to achieve the appropriate hermetic performance. A resistance seam welding the lid process produces a weld and 100% testing of hermeticity is performed on all manufactured parts in order to verify and guarantee the hermeticity.
