Abstract
Method and apparatus for joining two elongated members, such as rails, together by holding the rail ends in fixed relationship respective to one another while ramming powder metal between the confronting ends of the rails. Current flow occurs across the confronting faces of the rail and across the compacted powder, thereby elevating the temperature of the marginal rail ends and the compacted metal powder. The rams forge the hot metal powder and hot rail ends into a continuous mass. The method and apparatus can be used for building railroads, repairing defective rail lengths, and welding other elongated members together.
