Die vorliegende Erfindung schlägt ein Verfahren zum Herstellen eines Werkstoffverbunds vor, insbesondere eines Stahlwerkstoffverbunds, aufweisend die Verfahrensschritte: - Bereitstellen eines ersten Werkstücks und eines zweiten Werkstücks, - Erzeugen einer stoffschlüssigen Verbindung zwischen dem ersten Werkstück und dem zweiten Werkstück zur Bildung eines provisorischen Verbunds und - Walzen, insbesondere Warmwalzen, des provisorischen Verbunds zur Bildung des Werkstoffverbunds, wobei die stoffschlüssige Verbindung als Sollbruchstelle beim Walzen zumindest teilweise gelöst wird. A method for producing a composite material, particularly a steel composite material, may involve providing a first workpiece and a second workpiece, producing a bonded connection between said first and said second workpiece in order to form a provisional composite, and rolling said provisional composite in order to form the composite material. During the rolling, the bonded connection may be at least partially released, in the form of a predetermined breaking point. The rolling may be performed as hot rolling. Further, the method may involve substantially hermetically sealing the provisional composite by way of a sealant. The first and second work pieces, moreover, may be peripherally connected by way of the bonded connection along an edge area of a contact surface formed by the first and second work pieces.
