ABSTRACT:
An alignment gauge to facilitate the measurement of welded joints and the alignment of elongated structures including beams, pipes, rails, such as train rails and trolley car rails. The alignment gauge has five basic components, a base, an upright member and three dial indicators. The dial indicators are fastened along the top of the base, one at the center and one to each side of the center equally spaced from the center. The dial indicators have actuating plungers which pass through openings in the base and protrude through the bottom of the base. The upright member is mounted to the top of the base. It protects the dial indicators. The bottom of the base is placed on a calibration standard and dial indicators are adjusted to zero by a zero adjustment. With the dial indicators adjusted to zero, the alignment gauge is placed on the elongated structure with its center over the welded joint. The base has a channel in the center of the bottom surface that provides clearance for the welded joint. The center gauge provides a reading depicting the deviation in the welded joint and outside gauges display deviations of the joined elongated structures.
