Abstract

The invention relates to the joining of flat products of metallic materials to be interconnected overlapping. The joining takes place in a roll nip into which the flat products to be interconnected are introduced at an acute angle. Before they are pressed on one another in the roll nip, they are heated on their facing surfaces by radiation energy, but not melted. By a suitable profiling of at least one roller generated surface or one flat product the surface pressing is limited to the zone of the overlap joint and any flow of material transversely of the direction of the overlap joint is prevented.
