ABSTRACT:
A method is disclosed for producing an electric deposition foil producing drum for producing an electrically deposited metallic foil having a high quality. An opening tip end portion (14) opened toward the inside is formed in an inner surface portion of a joint portion (13) of an outer skin (12) made from a planar material in the form of a cylinder. The opening end portion (14) is welded from inside, and subsequently, the welded portion (15) and a portion close to the welded portion are bulged outwardly. A layer is welded in a recess (17) formed by the bulging work while cooling the outer surface of the outer skin. Subsequently, the welded layer is peened under a hot or cold work. Subsequently, the peened portion (18) is annealed. It is possible to obtain further advantages by using a welding means which does not require a welding rod for the welding of the joint portion (13).
