Abstract

PURPOSE:To simply form a joint with high adhesive strength with high reliabil ity by carrying out simple pretreatment on the joining surface and afterward, interposing insert metal therein to press and heat the joining surface. CONSTITUTION:The tapered joining surface 2 is formed between a ductile cast iron pipe 1 and a cast iron flange member 3 by machining. Then, insert metal foil is inserted into said joining surface 2 and a joining part is heated in an air atmosphere while applying the pressing force thereon and afterward, cooled. In this case, since the melting point of the insert metal is lower than that of cast iron, when the heating and pressing force are applied on the joining surface via joining material, the insert metal is molten and afterward, this molten metal is spread all over the area of the joining surface 2 and subjected to diffusion infiltration into the joining surface 2 and some deformation is given to the cast iron pipe 1 by the pressure and the joining with the flange member is solidified.
