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 ...

This paper discusses quantitatively the effect of indiscriminate (random phase-angle) switching in the primary of a resistance welder. The current and power transients occurring because of ``off-angle'' switching are investigated through oscillographic records of transients in loads built up to simulate actual welder-head loads as nearly as possible ...

The Resistance Welding Circuit
Transactions of the American Institute of Electrical Engineers, 1936This paper treats in something of an elementary fashion some of the problems encountered in the practical application of the resistance welding circuit, considering especially the electrical constants and variables involved. The lack of available literature on this subject inspired the preparation of this paper.

Welding Characteristics in Deformation Resistance Welding
SAE Technical Paper Series, 2008<div class="htmlview paragraph">Deformation Resistance Welding (DRW) is a process that employs resistance heating to raise the temperature of the materials being welded to the appropriate forging range, followed by shear deformation which increases the contacting surface area of the materials being welded.

Abstract Resistance welding is a group of processes in which the heat for welding is generated by the resistance to the flow of an electrical current through the parts being joined. This chapter discusses the processes, advantages, and limitations of specific resistance welding processes, namely resistance spot welding, resistance seam ...

Predetermination of Temperatures in Resistance Welds
Transactions of the American Institute of Electrical Engineers, 1939ONE of the most important variables in the resistance welding process is the temperature obtained in the region of the weld. If this temperature is too low, the parts will not unite; and if it is too high, a burned weld will result. Besides the necessity for the proper temperature at the surfaces to be joined, it is often essential to bring a ...
