A method of forming an elongated tubular blank into a tubular structural component having a predetermined outer configuration, the method comprising: providing a shape imparting shell (66) from a low permeability, rigid material which includes an inner surface defining the predetermined shape, plugging the open ends of the tubular blank (A), placing the plugged blank into the shell, and forming the tubular blank into the tubular component by inductively heating axial portions (10, 12) of the blank by axially spaced conductors adjacent the shell while or before forcing gas at a high pressure into the plugged blank until the blank conforms to at least a portion of the inner surface of the shell to form the structural component.

L'invention concerne un procédé de transformation d'une ébauche tubulaire allongée en composant structurel tubulaire possédant une configuration extérieure prédéterminée. Ledit procédé consiste à utiliser une coquille (66) de façonnage faite d'une matière rigide à faible perméabilité, comprenant une surface intérieure définissant la forme prédéterminée, à boucher les extrémités ouvertes de l'ébauche tubulaire (A), à placer l'ébauche bouchée dans la coquille, et à transformer l'ébauche tubulaire en composant tubulaire en chauffant par induction les parties axiales (10, 12) de l'ébauche au moyen de conducteurs axialement espacés adjacents à la coquille, pendant ou avant l'introduction de gaz à haute pression dans l'ébauche bouchée, jusqu'à ce que l'ébauche se conforme à au moins une partie de la surface intérieure de la coquille de façon à former le composant structurel.
