PURPOSE:To provide a welding method for a metal base composite material having high welding strength. CONSTITUTION:In a method for welding metal base composite materials 1 dispersed with inorganic materials finely in the base metal, a metallic planar body 3 is interposed between the butted faces of the metal base composite materials 1, the metallic planar body 3 is irradiated with high energy beam such as an electron beam 5, the interface between the metallic planar body 3 and the metal base composite material 1 is melted, solidified, and welded. Accordingly, since the electron beam 5 is high in energy density, a beam focusing can be converged and the metallic planar body 3 is irradiated with the electron beam 5, only the metal matrix part is melted, solidified and welded without damaging the phase dispersed with inorganic material and the high welding strength can be obtained. |
