ABSTRACT:
A self-propelling apparatus, suitable for use in automatic horizontal position welding of a large-sized square steel column such as architectural steel column, has a welder unit, travelling rollers and a seam tracking device. The travelling rollers are magnet-based rollers (1, 1') which are so arranged to hold the upper surface of the steel column and are mounted on a mounting plate (7). The mounting plate (7) is connected to the seam tracking device (6) through a rotational pivot (8) which is preloaded by a spring (9). The spacing between the travelling magnet rollers (1, 1') preferably ranges between 100 and 200 mm.
