Claim 13:
14. A method of friction welding a blade to a rotor element of an aircraft turbomachine, comprising the following steps:
a. providing a tooling according to claim 1;
b. providing a friction welding machine comprising a vibrating plate;
c. attaching the central part of the tooling to said vibrating plate;
d. arranging a portion of said blade to be welded in the bore of the fixed jaw body, so that the bearing surfaces come into contact with said blade;
e. bringing into contact the movable bearing surface of the movable jaw with said blade;
f. pressing said blade between the movable jaw and the fixed jaw body by means of the pressure means;
g. bringing into contact said blade and said rotor element;
h. actuating the friction welding machine so as to induce a relative movement between said blade and the rotor element to reach a welding temperature;
i. stopping the vibrating plate and pressing said blade against said rotor element so as to join them together; and
j. releasing said blade from the tooling.
