Abstract
A method of friction welding an airfoil () onto a rotor disk of a turbine engine, the disk having at its outer periphery a projecting stub () onto which the airfoil is to be welded, the method comprising a step consisting in mounting chocks () on leading and trailing edges of the stub, the method being characterized in that, before friction welding, the chocks are secured to the stub by welding, and in that during the friction welding operation, the beads of welding () between the chocks and the stub are expelled, at least in part, in seams of material () that form around the connection zone between the airfoil and the stub and that are subsequently to be removed or eliminated, e.g. by machining.
