The weight of capacitor energy storage resistance welding

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 are the advantages of a capacitive resistance welder?

Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds. 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.

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 rical circuit for capacitor discharge welding?

rical circuit for capacitor discharge welding is provided in Figure 2. The circuit incudes a primary capacitor (C), charged to an initial voltage (Vo), a transformer with wind gs ratio (N), a secondary inductance (Ls), and a load resistance (Rs). Vo (volts), C (farads), N Ls (henrys), and R s(ohms) are the charge voltage, capacitance, transform

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.

How can a capacitive discharge welding circuit be analyzed?

2. Schematic Representation of a Capacitive Discharge Welding CircuitThe current response of this circuit can be analyzed by reflectin the primary elements (capacitance, charge voltage) onto the secondary. The basic approach has been employed previously using haser analysis to estimate magnetic fluxes in wel
