  • Inertia welding process for making an anode assembly
    Patent number: 4129241
    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.
