Abstract Resistance spot welding (RSW) is a process in which faying surfaces are joined in one or more spots by the heat generated by resistance to the flow of electric current through workpieces that are held together under force by electrodes. This article discusses the major advantages of spot welding and the three principal elements,

Resistance Spot Welding in the Caravelle
Aircraft Engineering and Aerospace Technology, 1962AS a result of experience gained from the construction and operation of the Armagnac, Sud Aviation decided to make use of resistance welding for the construction of the Caravelle rear‐engined airliner. The Armagnac employed more than 150,000 spot welds, and although the welding machines used were of a comparatively early design, the results obtained ...

Welding force as a variable in resistance spot welding control
Proceedings of 2013 2nd International Conference on Measurement, Information and Control, 2013This paper presents research about the possible usage of welding force for the estimation of the weld strength. Other signals like welding current or electrode displacement are commonly used for this purpose. Our previous research has however shown that welding force is a very good indicator of expulsion occurrence.

Measurement and Effect of Contact Resistance in Spot Welding
Transactions of the American Institute of Electrical Engineers, 1946SPOT WELDING consists essentially of clamping two pieces of sheet metal between two copper electrodes and passing through the pieces an electric current of sufficient strength to fuse them together at the spot where the current is most concentrated. Spot welding is the simplest of the electric resistance-welding processes which depend upon the Joule ...

Forging force in resistance spot welding
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2002This paper studies an intentional force increase during the process of resistance spot welding (RSW). Known for decades, the forging force as a way of influencing weld quality has rarely been applied in the automotive industry. There has been little research in this area.
