Summary: | A method includes producing sheet steel products, in which steel blanks or steel strips of different thicknesses and/or material grades are welded together along a joint formed by edges of the steel blanks or steel strips. In order that the welding seam of such a sheet steel product does not lose the hardened microstructure obtained by abrupt cooling during warm forming with heating to an austenization temperature, before the welding process, a viscous liquid, such as a paste, or a solid, pulverulent, or aerosol-like substance that contains at least one component that increases the strength of the weld seam that is to be produced, is applied to at least one weld edge of the steel blanks or steel strips that are to be welded together. |
