Abstract: A composite substrate for use in a rotating x-ray anode tube consists of a graphite member joined to another member to which a target anode is affixed.

Abstract: A two step inertia welding process is employed to join the stem to the substrate of a disc thereby forming an anode assembly for a rotating X-ray anode tube. The abutting surfaces to be joined are rubbed together to heat the substrate to an elevated temperature, at which time the weld joint is formed by inertia welding.
