A method for repairing a turbine blade (10) wherein the tip (16) of the blade is removed (41,43) and a replacement cap is attached by welding (49). The cap may consist of a plate (48) attached by welding and a squealer (54) formed by depositing weld material (52), as illustrated in Figure 3. The plate and/or squealer may be formed from a material different from the material of the airfoil portion (42) of the blade in order to optimize the performance of the blade.
La présente invention concerne un procédé de réparation d'une aube (10) de turbine dans lequel on retire (41, 43) l'extrémité (16) de cette aube et on fixe un capuchon de remplacement par soudage (49). Ce capuchon peut consister en une plaque (48) fixée par soudage et en un siffleur (54) formé par un dépôt de matériau de soudure (52), comme le montre la figure 3. Cette plaque et/ou ce siffleur peut être fabriqué dans un matériau différent de celui de la partie du profil (42) de l'aube de façon à optimiser les performances de cette aube.
