Abstract
An electrode orientation checking apparatus includes a machine stand attached to a seam welding apparatus from which one roller electrode of a set has been removed, a positioning guide and a set of distance sensors that are provided on the machine stand, and a calculating section. A positioning surface of the positioning guide is fixed at a position corresponding to a portion of an outer circumferential surface of the one roller electrode before being removed, the portion lying on a line segment connecting rotational centers of the roller electrodes. The distance sensors are respectively fixed forward and backward of the positioning surface in a progression direction of the roller electrodes. The calculating section calculates data for acquiring a direction of the line segment relative to the stacked body.
