A clad steel plate is produced by superposing a backing steel and a cladding metal having their contact surfaces cleaned, with a metallic foil or a metallic plating layer applied onto the contact surface of at least one of the backing steel and the cladding metal interposed as a medium layer between them, welding the superposed backing steel and cladding metal together along contact lines between their peripheral edges into a composite slab leaving at least one portion of the contact lines unwelded, exhausting any air remaining between the contact surfaces of the backing steel and the cladding metal by cold rolling or cold pressing under light reduction, welding the one or more unwelded portions on the peripheral edges together to isolate the contact surfaces from the external atmosphere, heating the composite slab to a rolling temperature, and hot-rolling it. |
