    摘要： 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. The metal bar composite is trimmed by a cutting operation, and the pressure fluid inlet area of the metal bar composite is cut off after the widening has taken place. In order to reliably manufacture a flangeless hollow body in a simple manner from two metal bars, the metal bars are seam-welded before entering into the forming tool, and the resulting metal bar composite is then trimmed by a beam welding process in the weld seam. Then for the expanding forming, the metal bar composite is charged into the forming tool such that its trimmed edges are situated within the die sinking of the forming tool, with the metal bar composite being clamped in only in the area of the pressure fluid inlet.

    摘要： A tailor welded blank for use in a fluid-forming operation includes a first sheet element having a physical characteristic with a first value and a second sheet element having the physical characteristic with a second value different from the first value. The first and second sheet elements are welded together at at least one weld region to form at least a portion of a tailor welded blank. When the tailor welded blank is processed in a fluid forming process, the first and second values of the physical characteristic result in said first and second sheet elements having approximately equal effective strength values such that said first and second sheet elements deform at an approximately equal rate during the fluid forming process and local thinning and failure initiation is reduced at the at least one weld region and throughout the first and second sheet elements.

    摘要： An apparatus for forming blanks having two thicknesses separated by a blank step includes a forming tool defining a binder surface that is characterized by a tool step, a first region on a first side of the tool step, a second region on a second side of the tool step, and a bead segment having a surface contiguous with the second region. The bead segment is configured to pinch material from a blank into any gap created between the tool step and the blank step caused by misalignment of the blank in the tool, thereby ensuring an effective seal to form the blank against a forming surface.
