1. A tooling for holding a blade during friction welding thereof to a rotor element of an aircraft turbomachine, comprising:
a fixed jaw comprising:
a central part adapted to be attached to a vibrating plate of a friction welding machine;
two arms substantially parallel to each other, separated by a distance d for receiving at least a portion of the blade and substantially perpendicular to said central part; and
a fixed jaw body disposed between the two arms, comprising bearing surfaces and a bore for receiving at least a portion of the blade, the bearing surfaces being intended to come into contact with faces of the blade;
the tooling further comprising:
a movable jaw configured to slide along the two arms and comprising a movable bearing surface configured to contact a face of the blade; and
pressure means configured to move said movable jaw towards the fixed jaw body to press the blade between the movable jaw and the fixed jaw body.
