Capacitor Discharge Welding
This is used for welding of studs, welding of thermocouples, etc. on the base metal. A low voltage, high amperage electrical discharge from a capacitor, supplies the arc energy. The current creates an arc, which melts the entire face of the studs & thermocouples and the same area of the work. The stud is then driven at a veryhigh velocity into the molten pool.
The Brasses 70/30 brass also called as cartridge brass contains 70% copper and 30% Zinc. This is employed for cartridge cases, sheet fabrication, and condenser tubes and for u
