Abstract

A method and a system of forming a workpiece assembly including an intermediate element between first and second workpieces. A ring element is included in or on the intermediate element. The ring element is for rotating the intermediate element about the intermediate elements axis. With heating elements positioned between the intermediate element and the first and second ends of the first and second workpieces, portions of the intermediate element and the first and second workpieces are heated to a predetermined hot working temperature, in an inert (non-oxidizing) atmosphere. While the heated portions are at the predetermined hot working temperature, and while the intermediate element is rotated about its axis, one or both of the first and second workpieces are moved axially, to engage the first and second ends with the intermediate element.
