ABSTRACT

A process for orbital friction welding of a blade to a stub on a turbomachine
rotor disk, comprising the following successive phases: friction of the blade
against the stub with application of a force friction normal; forging of the
blade against the stub with application of a normal forging force; wherein the
normal forging force is greater than the normal friction force and essentially
constant throughout the forging phase.
