EQUIPMENT FOR RESISTANCE WELDING-Stored energy equipments
Energy can be stored and further utilised for welding.
One method of storing energy is in capacitors electrostatically. Such machines were introduced during the World War II. In India also they are now being manufactured. Energy can be stored electro - chemically in batteries. In Japan, a circuit has been developed to utilise car batteries for this purpose.
Other modes of storing energy are
- in a magnetic circuit (or a reactor) electromagnetically and
- in a rotating apparatus electromechanically (Fly wheel).
