Zusammenfassung:	The present invention relates to a method for making a metal reinforcement (30) for the leading edge or trailing edge of a turbine engine blade, comprising in sequence: a step (44) for positioning a preform (26, 70) by means of equipment (60) positioning said preform (26, 70) in a position such that said preform (26, 70), at one end thereof, has an area (28, 72) which is capable of receiving a filler metal; and a step (46) for constructing a base (39) for said metal reinforcement (30) by hard-surfacing with filler metal in said area (28), in the form of metal beads. La présente invention concerne un procédé de réalisation d'un renfort métallique (30) de bord d'attaque ou de bord de fuite d'aube de turbomachine comportant successivement: - une étape (44) de positionnement d'une préforme (26, 70) au moyen d'un outillage (60) positionnant ladite préforme (26, 70) dans une position de sorte que ladite préforme (26, 70) présente à une extrémité une zone (28, 72) apte à recevoir du métal d'apport; - une étape (46) de construction d'une base (39) dudit renfort métallique (30) par rechargement de métal d'apport dans ladite zone (28), sous la forme de cordons de métal.
