- 38 - METHOD FOR PRODUCING A CLAD PLATE BY HOT-ROLLING ABSTRACT OF THE DISCLOSURE In a method for producing a clad plate by rolling an improvement comprises: a base material, a cladding material, and a cover material overlaid on each other to form a multi-layer structure, and after cleaning joining surfaces of the materials, the cover material is welded to the base material along the periphery thereof, thereby sealing and fixing the cladding material between the cover material and base material, and forming a multi-layer assembly. A member for preventing warp is overlaid over an outer surface of the cover material via a separating agent, and the member for preventing warp and the base material are fixed to one another by welding along the periphery thereof, thereby forming a blank for rolling. The blank is hot-rolled, a rolled article is cut along its periphery to separate the means for preventing warp, and subsequently, the cover material is removed by machining, grinding, or pickling.
