THE OUTPUT of resistance-welding machines is generally determined by Joule's law W=RI2 where R is the resistance of the heated metal being welded and I is the current flowing during the welding operation. With the majority of machines, welding current is determined by the internal impedance of the machine, the resistance of the weld being but a small ...

In the current chapter we debate a joining process called resistance spot welding which finds many applications ranging from the automobile industry to robotics. In the first part of the chapter we present the construction of a non-local mathematical model illustrating the phase transition occurs during this joining process.

Note: Resistance spot welding using a microgripper
Review of Scientific Instruments, 2013Interest in thin-film nanostructures as building blocks for nanoelectronics and nanoelectromechanical systems (NEMS) is increasing. Resistance spot welding (RSW) on a nano or micro scale can play a significant role; similar to that of its macro counterpart for forming connections in device assembly processes. This Note presents a novel micron scale RSW

Control of resistance spot welding
Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999This paper discusses recent progress in the development of a feedback controller for the resistance spot welding process. Two key elements of our control architecture are: operating condition detection and nugget growth estimation. In this paper the operating condition problem is addressed with respect to three well-defined operating conditions.

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 ...

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,

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 ...
