# Orbital friction welding method of a blade to a stub on a turbomachine rotor disc

## 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.
