出装置。[Claims for Utility Model Registration] A part of the annular part of the workpiece to be welded is held between a pair of roller electrodes under pressure, and a voltage is applied between these electrodes while rotating the electrodes, thereby welding by a copying device. This is attached to a seam welding machine with a copying device that sequentially welds the welded parts guided to the position so that the weld line indicating the welding trajectory forms an annular welded part, The distance to the workpiece at the start of welding on a predetermined measurement line that intersects the traveling direction of the part to be welded, and the workpiece on the measurement line when the welding start point of the part to be welded has gone around and returned to the welding position. and a determination unit that generates an abnormal signal when the difference between the distances to the two workpieces detected by the displacement sensor is equal to or larger than a predetermined value smaller than the width of the weld line. A welding line trajectory deviation detection device characterized by:
