  • Publication number: 20080000947
    Abstract: This invention relates to a part-holding device in a method for repairing a blade of a monobloc bladed disc of a turbo-machine, through electron-beam welding of a patch onto the blade along a junction plane. The device comprises means for supporting the disc and adjustable means for holding the blade and the patch, the latter comprising a platen supporting means for holding the blade and means for holding the patch, arranged such that the space located above the junction plane allows for an electron beam to pass. Implementing the present invention, the relative positions of the blade and the patch are set using holding means that are all supported by a same platen, while leaving some space allowing for an electron beam to pass. Such a device is simple and reliable.
