Abstract:
A method of forming an elongated metal blank into a structural component having a predetermined outer configuration. The method includes providing a shape imparting cavity or shell section formed from a rigid material which includes an inner surface defining the predetermined shape, placing the metal blank into the cavity or shell section, and forming the metal blank into the component by heating axial portions of the metal blank and forcing a fluid at a high pressure into the metal blank until the metal blank at least partially conforms to at least a portion of the inner surface of the cavity or shell section to form the structural component.
