The charging resistor of the energy storage welding machine turns red

What is capacitor discharge welding?

Capacitive discharge welding, particularly for large-scale systems, is typically done using film-type capacitors. These capacitors store energy along alternating plates separated by a dielectric film. Charge is stored statically along the lengths of the plates. The basic configuration of the film capacitor is provided in Figure 1.

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

How does CD welding work?

With CD welding, the main energy is stored in a capacitor arrangement. In application, that energy is discharged through a transformer creating again low voltage – high current power for welding. CD welding does differ from conventional resistance welding in a number of ways(1).

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

What is the difference between alternating current and CD welding?

Conventional systems provide some variant of alternating current to a transformer arrangement. The transformer arrangement produces low voltage, high current power that is suitable for resistance welding. With CD welding, the main energy is stored in a capacitor arrangement.

What is capacitive discharge or CD welding?

Capacitive discharge or CD welding is a variant of resistance welding(1,2). The process differs from the conventional variants largely in the type of power supply used. Conventional systems provide some variant of alternating current to a transformer arrangement.
