6 FAQs about [How big is the resistance of the automatic welding capacitor]
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 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 resistance welding?
Resistance Welding is a thermo-electric welding process where the weld is made by a combination of pressure and current. The process is a simple joining of metals by applying controlled pressure and passing current for a length of time through the metal area to be joined.
