摘要

Process for applying a corrosion protection layer to a cut surface of a flat metallic material comprises subjecting the cut surface to a metallic and/or plastic corrosion protective agent with the introduction of thermal and/or electrical energy. The agent is melted using the energy and then applied in the molten state to the cut surface. An Independent claim is also included for a device for applying a corrosion protection layer to a cut surface of a flat metallic material comprising a laser arrangement and an application unit. Preferably the metallic and plastic corrosion protection agents are simultaneously applied or laterally after each other onto the cut surface. The cut surface is formed as an edge of the metallic flat material with a thickness of 0.1-10 mm.
