AUTOMATIC WELDING, GRINDING, AND HANDLING OF LONG RAILS

An electric, automatic, flash welding machine, designed by a Swiss firm, is being used to weld 132-lb., 39-ft. rails for the Louisville & Nashville Raolroad. Rail ends are ground to remove rust, then heated to plastic consistency and forced together with a 30-ton force. A 50-ton hammer-blow forces foreign matter, gases, and surplus molten metal from the weld. An automatic grinder removes mill-scale and hand-grinders are used to remove any remaining roughness. The welding unit, grinder, and pusher are mounted in tandem on a 60-ft. all-steel car. About 60 welds per 8-hr. shift can be made by a crew of 8.
