Abstract

PURPOSE:To make the slip caused on the interface between an outer pipe and a core metal large and to metallically and firmly join both pipe and core by drawing while making the inner diameter of the outer pipe to be larger than the outer diameter of the core metal to the degree of forming a clearance between the outer pipe and the core metal. CONSTITUTION:By making the inner diameter d0 of the outer pipe 2 large, the clearance is formed between the outer diameter Di of the core metal 4 and d0. The blank material worked by the abovementioned method is passed through a die 6 and the wire drawing is performed. In the stage of the wire drawing, the large slip is generated between the inner surface of the outer pipe 2 and the outer periphery of the core metal 4, to bond metallically and firmly. By this method, a product excellent in joining strength is obtained.
