  • Method of making large volume hollow bodies
    Patent number: 6684475
    Abstract: A large dimension hollow body such as a fuel tank is formed from cold deformable sheet metal by cutting a sheet metal blank of a conformation matching the hollow structure to be formed and which has a nonuniform cross section between its ends. The sheet metal blank is then formed into a three-dimensional shape closed at one end and subjected to hydrostatic forming, whereupon the other end is closed optionally after insertion of an object to be received in the tank such as a fuel pump. The welding of the edges of the blank together and the application of the caps can produce pressure-tight weld seams and can be effected by laser-beam welding or tungsten inert gas welding.
    Type: Grant
