ABSTRACT:
Electrical resistance spot welding is controlled by stopping the welding current upon detection of indentation of the work pieces by the electrodes. Indentation is detected indirectly by monitoring the deformation in one or both electrode holders. The piston of the welding gun cylinder is prevented from displacing in direct proportion to displacements of the electrodes during formation of the weld so that the squeezing force applied by the electrodes to the work piece, and therefore the deformation in the electrode holders, varies as a function of electrode displacements.
