Abstract
A method for producing an overlap composite material from sheet metal is described, wherein a first sheet of a first metal and a second sheet of a second metal, which has a lower strength than the first metal, are positioned one above another in an overlapping manner in an edge region, and are then joined by rolling. The first sheet has a wedge-shaped edge in cross-section. The second sheet is to be positioned with its edge on a side surface of the first sheet formed by the wedge-shaped edge. The side surface formed by the wedge-shaped edge of the first sheet has a greater width than the side surface of the edge of the second sheet positioned on the said side surface of the first sheet, and, after positioning, the sheets are joined by rolling.
