ABSTRACT:
A welding apparatus including, generally, a vertical clamping assembly having an upper and a lower clamping assembly for each of two rail sections to be welded together. These vertical clamping assemblies clamp and vertically align the running surfaces of the two rail sections, by establishing the running surfaces at a pre-determined stop level. The welding apparatus also includes a horizontal centering and aligning apparatus which has a first pair of clamping arms which engage the rail base and pre-center the rail sections with respect to one another and to the welding apparatus. The apparatus also includes a pair of spaced apart clamping arms associated with each of the rail sections which are operable to both laterally clamp the rail heads of the respective rail sections and to horizontally or laterally align the rail sections with respect to one another. Once aligned, the ends of the rail sections are welded together.
