PURPOSE:To weld easily a molten metal to a long-sized metallic body by dipping continuously the long-sized metallic body in a vessel for the molten metal and grinding and activating continuously the surface of the long-sized body by a grinding roll disposed in the vessel. CONSTITUTION:A long-sized metallic body 1 formed of iron or the like which is guided by guide rollers 2 and is polished by brushing is introduced through a gate 4 into a vessel 3 for a molten metal of copper or the like and while the long-sized body is continuously moved toward the arrow direction, said body is brought into contact with the molten metal. The surface structure of said body 1 is further continuously ground and chipped away by a grinding roll 6 dipped and disposed in said vessel 3. The activated surface is then exposed on the surface of the body 1 and is joined to the molten metal in contact therewith. The molten metal welded onto the body 1 is throttled by a throttling roll 5 to control the thickness of the welded layer and thereafter the long-sized body is discharged to the outside to solidify the molten metal. The long- sized laminated body of the metal is thus obtd. After the body 1 is ground in the vessel 3, said body is drawn by rolling rolls in succession thereto to expose the fresh activated surface by which the two metals are more easily welded. |
