Principle of energy storage spot welding

What is a spot welder used for?

of larger, more powerful, and more costly welding transformers.Spot welding is most commonly used in the automobile manufacturing business, where it is nearly routinely used to join the sheet metals of car frames. Spot welders can also be fully automated and many o

Why is spot welding important?

d electrical conductivities necessitate larger welding currents. This necessitates the us of larger, more powerful, and more costly welding transformers.Spot welding is most commonly used in the automobile manufacturing business, where it

What is resistance spot welding?

body of automobiles, which are numerically controlled nowadays. Resistance spot welding works on the principle of Joule’s law of heating, where the heat generat d is directly proportional to the square of the welding current. This welding technique is generally used

How is a thyristor used in a spot welding machine?

In an AC pulse spot welding machine, the thyristor is controlled by the single-chip microcomputer to intercept the AC pulse voltage for the primary coil of the welding transformer. The transformer then converts the high-voltage pulse into a low-voltage large current and outputs it to the spot welding needle for discharge spot welding.

What is a resistance spot welding s Tup?

ntain the pressure to allow the weld metal to cool and solidify. The applied weld times normally range from 0.01 to 0.8 s depending on the thickness of the m tal, the electrode force, and the electrode tip diameter [2, 3].The resistance spot welding s tup mainly consists of tool holders and copper alloy electrodes. The tool olders ac

What is the difference between resistance spot welding and projection welding?

nsure quality welds.5. Modifications of resistance spot weldingA modified version of resistance spot welding has been developed which is known as projection welding. The weld is localized in projection welding by using raised areas, or projections, on one or both of the metal sheets to be connected. Heat is con-centrated at these projections,
