In-track rail welding system
An improved in-track welder eliminates conduction path force members and employs separate bridging current path conductors for DC welding of rail ends. The enhancement allows for an increased closure distance, thus improving cold-weather operations. An increased allowable distance between conduction contacts allows for the incorporation of an internal shear member for more efficient finishing of welds. The force members may be optimized for strength rather than electrical properties, and are comprised of relatively small diameter alloy steel rods.
