PROBLEM TO BE SOLVED: To provide a joining method of titanium and aluminum which does not require special equipment and a special joining environment and makes joining in the atmosphere possible. SOLUTION: Prior to joining between a titanium material 1 of a base metal and an aluminum material 2, surface defatting and a blast treatment is done on a joining face of a titanium material side, a thermal spray film layer 3 of aluminum base is formed thereon, further subjected to a fusion diffusion treatment with TIG welding. The titanium material 1, which has the thermal spray film layer after the fusion diffusion treatment as a joining face, and the aluminum material 2 are butted, both are joined with using TIG welding using an aluminum filler material or brazing joing using brazing filler metal. |
