Abstract: The invention relates to a method for producing components from sheet metal, wherein at least one patch sheet (2) is placed on a base sheet (1) to form a material doubling and is positionally securely fixed, the component unit thus formed, comprising base sheet (1) and patch sheet (2), is heated to a temperature suitable for hot forming and is then hot-formed to form the component and, preferably subsequently or simultaneously, is subjected to partial or total cooling or quenching for the purpose of a specific structure conversion, wherein, for the purpose of improved corrosion protection, the base of sheet (1) in the contact region of the patch sheet (2), or the patch sheet (2) on the side thereof facing the base sheet (1), or both base sheet (1) and patch sheet (2) in the corresponding area are coated with an anti-corrosion coating (6) that is resistant to the temperatures occurring during the hot forming, before the patch sheet (2) is placed on the base sheet (1).

Abstract: First and second metallic parts are joined by first providing a face of the first part with a formation projecting from and forming only a limited portion of the face and then connecting the first part with the second part by fixing the formation to a face of the second part such that the formation holds the first and second parts in a preassambled position with the faces of the first and second parts confronting and out of contact with each other at a predetermined spacing. Then the two spaced and confronting faces of the first and second parts are coated, after which the first and second parts are pushed together with deformation of the formation of the first part into a final-assembly position with the coated faces pressing directly against each other. Then the first and second parts are permanently joined together.

Abstract: The invention relates to a shaped part (1) composed of metal, in particular steel, for a motor vehicle, comprising a hole (2) for a fastener and a perforated reinforcement plate (3) composed of metal, in particular steel, that covers the hole (2) and is fastened to the shaped part (1), wherein the reinforcement plate (3) is mounted at a spacing (4) from the shaped part (1) and is attached to the shaped part (1) only in at least one limited portion.
