ABSTRACT:
A method for inertia welding axially symmetric articles while controlling the gripping force applied to the rotating component is described. A spacer inserted into the rotating headstock creates an alternative path for the axial force in excess of that required for causing gripping of the rotating component, and thus minimizes distortion of the inertia welded article. This is particularly useful in welding high strength superalloy articles, where extremely high axial forces are required to produce an adequate weld joint.
