self-leveling welding tractor equipped with a sensor that measures the angle of elevation or depression angle of the tractor

摘要

The present invention self-leveling welding tractor and welding system which includes a sensor for measuring the angle of elevation or depression angle of the tractor I provide. A describes the use process of welding tractor 110 to maintain a predetermined elevation or depression angle between the welding tractor 110 and circumferential welding work. For supplying welding to the welding assembly wire 220; base unit 150; welding was operatively coupled to base assembly 160: a rotatable body a welding tractor 110 for a circumferential weld around the longitudinal axis welding wire supply; including; and operably linked to the base portion, by measuring the angle of elevation or depression angle of a welding tractor level sensor 140 for identifying the degree of horizontal planarity.BACKGROUND 1
