Abstract A method is provided for repairing a metallic turbine component which includes at least two airfoils interconnected by a mid-span shroud. The method includes: (a) applying a reinforcement plate to the mid-span shroud; (b) applying braze material to at least a portion of a perimeter of the reinforcement plate; (c) heating the component to melt and flow the braze material between the reinforcement plate and the mid-span shroud; and (d) allowing the braze material to cool and solidify so as to bond the reinforcement plate to the mid-span shroud. Linvention concerne une méthode de réparation dun composant de turbine métallique qui comprend au moins deux surfaces portantes interreliées par un carénage détendue moyenne. La méthode comprend : (a) lapplication dune plaque de renforcement au carénage détendue moyenne; (b) lapplication dun matériau de brasage à au moins une partie dun périmètre de la plaque de renforcement; (c) le chauffage du composant pour fondre et écouler le matériau de brasage entre la plaque de renforcement et le carénage détendue moyenne; et (d) laisser le matériau de brasage refroidir et se solidifier pour lier la plaque de renforcement au carénage détendue moyenne.
