Abstract: A process for manufacturing a hollow body made of two mutually welded together metal bars which are flatly disposed on one another. Within an internal high-pressure forming tool in a closed position, the metal bars are widened by introducing a pressure fluid under a high pressure into the parting line existing between the metal bars, until they are placed on the die sinking of the forming tool defining the final contour while forming the hollow body.
