A process for near-net-shape manufacturing of a formed metallic work piece with armoring, with the armoring having different properties than the basic work piece material, including the steps of providing an armoring blank; providing a basic work piece blank; arranging the armoring blank on the basic work piece blank; welding together a surface section of the work piece blank and the armoring blank, thereby creating a blank with an armored surface section; and forming the resulting blank with an armored surface section, thus producing a near-net-shape work piece contour by means of a process which is selected from the group comprising: forging, upsetting, electro upsetting, and extrusion, at a temperature in one of a cold, half-warm and warm temperature range, thereby producing a near-net-shaped formed armored work piece.
