Abstract: A grinding system includes a welding gun movable relative to a workpiece. A pair of clamp devices move relatively toward each other to clamp a workpiece. A welding tip is disposed on one of the pair of clamp devices. A detector detects a relative movement amount of the welding tip with respect to the other clamp device. A dresser grinds the welding tip. While the dresser is grinding the welding tip, a determinator determines whether to make the dresser end grinding the welding tip based on the movement amount detected by the detector. When the determinator determines to make the dresser end grinding the welding tip, an instructor instructs the dresser to end grinding the welding tip.

Abstract: The seam welding apparatus includes a pair of rotating electrodes, an electrode supporting frame, a distance measuring means, and a controller. The electrode supporting frame supports the pair of rotating electrodes. The distance measuring means is provided on the electrode supporting frame and measures a distance to an edge of the steel plate. The controller controls the robot to adjust a running direction of the rotating electrodes so that a deviation comes into zero when a distance actually measured by the distance measuring means deviates from a predetermined distance. Thereby, it is accomplished that the seam welding apparatus is downsized as well as uninfluenced by the surface state and/or shape of workpiece (steel plate).

Abstract: A grinding system includes a period determiner that determines, on the basis of a torque of a grinder of a dresser that grinds a welding tip, whether the current period is a grinding period in which the grinder is grinding the welding tip or a non-grinding period in which the grinder is not grinding the welding tip; and an anomaly detector that detects anomalies that are associated beforehand with each of the grinding period and the non-grinding period.

Abstract: A seam welding system includes a pair of roller electrodes. The pair of roller electrodes hold a to-be-welded object between circumferential surfaces of the roller electrodes, rotate while holding the to-be-welded object between the circumferential surfaces, and perform seam welding on the to-be-welded object when a current flows between the roller electrodes while rotating and holding the to-be-welded object between the circumferential surfaces. To an electrode movement mechanism, the roller electrodes are mounted. The electrode movement mechanism moves the roller electrodes along a welding line of the to-be-welded object. Drive sources respectively rotate the roller electrodes and a joint of the electrode movement mechanism. A controller controls an amount by which the roller electrodes rotate based on a torque change in the drive sources so as to keep torques respectively acting on the roller electrodes within a predetermined range.
