Abstract
A system for securing first and second metal workpieces to a central metal workpiece located therebetween. The system includes clamps to secure the first and second metal workpieces in coaxial alignment with the central metal workpiece, and the central metal workpiece is rotatable about its axis. Heating elements heat opposed ends of the first and the central metal workpieces, and opposed ends of the second and the central metal workpieces to a hot working temperature. While the opposed ends are at the hot working temperature, the heating elements are removed, and the opposed ends are engaged with each other, and the opposed ends of the central metal workpiece are rotated relative to the other opposed ends engaged therewith.
