Abstract

Metallic sheets, wires, bars or other products are descaled by sweeping their surfaces with one or more laser beams to detach an adhering oxide film along lines traced by the beam sweep. The film fragments, still loosely adhering at locations between the sweep lines, are then removed mechanically, chemically or electrolytically.
