Abstract

A resistance welding control system includes a pair of electrodes, a driving mechanism, and a control device. The control device includes a detector, a determining unit, and a stop controller. The detector is configured to detect a position of a first electrode of the pair of electrodes and a distance from the first electrode to a second electrode of the pair of electrodes in the approaching-separating direction while electricity is being passed between the first and second electrodes. The determining unit is configured to make a determination as to whether predetermined variation has occurred in the position or the distance. The predetermined variation indicates that a temperature of the member to be welded is at a feature point temperature. The stop controller is configured to stop the electricity passed between the first and second electrodes on the basis of a result of the determination.
