Capacitor energy storage type pressure welding machine capacitor

What is capacitor discharge resistance welding?

Capacitive discharge resistance welding uses large capacitors to store energy for quick release. Figure 1 shows a typical capacitor discharge curve. Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds.

What is capacitor energy storage welding?

The principle of capacitor energy storage welding is to use the energy slowly stored in the capacitor from the power grid. In a short period of time, the metal is heated and melted by discharging the welded workpiece through the resistance welding transformer.

What is a capacitive welder?

Capacitive welders deliver repeatable welds even during line voltage fluctuations. Spot welding relies on the principle of metal resistivity to heat and fuse metal. A large current is passed through the work piece. Energy is dissipated due to the metal resistance in the form of heat which melts and fuses weld materials. There are two phases to

What is a capacitor discharge spot projection welding machine?

The principle of the capacitor discharge spot projection welding machine is to charge and store a group of high-capacity capacitors through a small transformer in advance, and then discharge and weld the welding parts through a high-power welding resistance transformer.

What is a capacitive discharge welder?

Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material. The heat affected zone, where the properties of the metal have been changed from rapid heating and cooling, is localized to a small area around the weld spot.

What is a power supply capacitor?

At the heart of the power supply are capacitors with capacitance ranging from 20,000 to 200,000 μF. These large-value capacitors are designed to rapidly discharge a substantial amount of energy during the welding process.
