ABSTRACT:
A welding apparatus is provided which includes a rail member 5 installed along a side and a corner portion of a steel frame post, a pinion 46 mounted to a horizontally movable shifting member 50 such that even at the corner portion of the steel frame post 1 the pinion 46 is constantly held in mesh engagement with a rack 6 disposed on a side of the rail member 5, and a position holding roller 57 for guiding the shifting member 50 in a horizontal direction so that the distance between the rack 6 and the pinion 46 is kept constant. During the movement of the carriage, the distance between the rack and the pinion is kept constant to enable welding operations to be performed in succession with respect to side and corner portions of the steel frame post. Therefore, after a face-to-face welding operation at one side is completed, such a welding operation at the other side may be carried out without the necessity of removing the carriage from the rail member. This provides for improvement in operating efficiency, as well as quality improvement and stability with respect to weld work.
