Abstract

The invention relates to a process for the production of hollow components. For this purpose, an upper sheet 2 and lower sheet 3 are connected at their external edges in a manner sealed with respect to gas to form a sheet stack with a partial separating medium 5, 6 therebetween, and a gas supply 7, 8 to the mould seam is incorporated between the sheets of the sheet stack during the welding of the external edges. Subsequently, the mould seam is evacuated via this gas supply and is welded in the area without separating medium in a hot isostatic pressing process or an explosion compression process or a hot rolling at the diffusion welding temperature of the sheets. Finally, the sheet stack is blow formed to form a component in a closed heated mould, by the action of a gas pressure between the upper sheet and the lower sheet. Using this process, engine, aircraft and vehicle components can be produced. <IMAGE>
