[Composition] Manifold main body 1 and manifold flange 2 made of cast aluminum alloy And a branch pipe 3 made of an aluminum alloy and a carbon steel pipe for machine structural use, which has a smaller diameter than the joint insertion portion of the branch pipe in the joint fitting portion of the manifold main body portion and the manifold flange portion. Hole is formed, and this joint fitting part is heated to about 250 with a medium frequency induction heating device. At a stage of heating and expanding at around 0 ° C., the joint insertion portion is inserted into the hole having the expanded diameter dimension, and then the joint fitting portion and the joint insertion portion which are joined are cooled by the shrink fitting method. This is a structure in which the manifold body and the manifold flange are joined to the branch pipe. [Effect] The manufacturing cost can be reduced and the weight can be reduced. Secure joining is possible with inexpensive equipment. The thermal effects such as deformation and distortion can be suppressed to a minimum, and dimensional accuracy stability can be secured.
