SOLUTION: In the first step, friction stir welding is performed as an addition material is fed to welding parts for preventing the coarsening of the crystal grains of metallic materials accompanying the following fusion working (S01), and thereafter, fusion working such as MIG (metal inert gas) welding is performed (S02). The addition material to be added to the welding parts comprises a substance which is not chemically reacted with the metallic materials and also has a melting point higher than that of the metallic materials, and a substance whose miss-fit to the metallic materials is within ±15%. By the above procedure, the coarsening of the crystal grains caused by the fusion working can be suppressed, and their joining strength can be improved. COPYRIGHT: (C)2007,JPO&INPIT
