The invention relates to a method and a device for holding a metallic component to be connected, especially a gas turbine. The inventive method is characterised by the following steps: a metallic component (1) having a surface (2) and at least one working or joint surface (3) is provided; a case (5) comprising a recess which is used to receive the component (1) and has an inner surface (6) is provided; the component (1) is positioned in the case (5) in such a way that its surface (2) is surrounded by the inner surface (6) of the case (5), at a distance, forming a closed volume (8), and the working or joint surface (3) of the component does not face the volume (8); the volume (8) is filled with a foamable material (11); and the material (11) is foamed and cooled, forming a dimensionally stable foam structure. The invention also relates to a method for connecting a metallic component, especially a gas turbine, to another component.
L'invention concerne un procédé et un dispositif pour maintenir un élément métallique à assembler, notamment une turbine à gaz. Ledit procédé se caractérise par les étapes suivantes : préparer un élément métallique (1) comportant une surface (2) et au moins une face d'usinage ou d'assemblage (3) ; préparer un coffret (5) muni d'un évidement présentant une surface intérieure (6), pour loger l'élément (1) ; positionner ledit élément (1) dans le coffret (5), de manière que sa surface (2) soit entourée, avec un écart, par la surface intérieure (6) dudit caisson (5), afin de former un volume (8) fermé, et de manière que sa face d'usinage ou d'assemblage (3) ne donne pas sur le volume (8) ; remplir ledit volume (8) avec un matériau apte au moussage (11) ; faire mousser ledit matériau (11) et refroidir de manière à former une structure de mousse indéformable. L'invention concerne également un procédé permettant d'assembler un élément métallique, notamment une turbine à gaz, à un autre élément.
