摘要： A process of producing from an elongate tube a tubular structural component having a first longitudinal section integrally connected to a second longitudinal section, the second section being located at the end of the tube and being of a desired cross-sectional shape and size, the cross-sectional size of the second section being greater than that of the first section, the process including selecting a mandrel having a cross-sectional shape and size corresponding to the second section, relatively axially feeding said end of the tube over the mandrel in order to form said second section, the choice of the size of mandrel and the rate of feed and the axial pressure applied to said tube being controlled such that the wall thickness of the second section is on average at least 70 percent of the average wall thickness of the first wall section.

摘要： A hydroforming process for forming a component from an elongate tubular blank comprised of a deformable metal, the process including placing the blank in a die and sealing opposed ends of the tubular blank, heating the blank to a predetermined deformation temperature which is greater than 350.degree. C. but less than the melting point of the metal, supplying a gas at a predetermined pressure to the interior of the sealed tubular blank to cause deformation of said tubular blank at predetermined regions by drawing/stretching of the metal.
