Abstract
Geometries are described for joining superalloy articles by inertia welding. First and second hollow superalloy articles are joined wherein the first article has an inside and an outside diameter which are less than the inside and outside diameter of the second article. This produces a staggered joint geometry which results in curved 'S' shaped weld zone and beneficial control of the residual weld notch.
