Abstract (en)
[origin: WO2019042855A1] A method for producing an overlap composite material from sheet metal is described, wherein a first metal sheet (1) composed of a first metal and a second metal sheet (2) composed of a second metal which has a lower strength than the first metal are placed one on top of the other in overlapping fashion in an edge region and are then connected by rolling. Provision is made according to the invention for the first metal sheet (1) to have an edge which is wedge-shaped in cross section, and for the second metal sheet (2) to be placed with its edge against a side surface (3), formed by the wedge-shaped edge, of the first metal sheet (1), wherein the side surface (3) formed by the wedge-shaped edge of the first metal sheet (1) has a greater width than that side surface (4) of the edge of the second metal sheet (2) which is placed against said side surface (3) of the first metal sheet (1), and the metal sheets (1, 2) are connected by the rolling after the placing process.
