Abstract

A metal-reinforced layered composite includes at least one intermediate metal layer. The intermediate metal layer includes at least two at least partially overlapping metal foils which are joined to one another in an overlap region by at least one weld seam. There are no leakage channels and/or no continuous leakage channels at the weld seam of the metal foils in the longitudinal extent of the overlap region. At least one of the weld seams may have a course which at least at one point has a direction component at right angles to the longitudinal extent of the overlap region of the metal foils. The intermediate metal layer may be provided with at least one passage in the overlap region of the metal foils. A gasket, a gasket sheet, a metal layer and a method of manufacturing a layered composite are also provided.
