    Abstract: PROBLEM TO BE SOLVED: To provide a spot weld joint excellent in joint strength even when the spot weld joint is formed by performing spot weld of high strength steel sheets.SOLUTION: There is provided the weld joint formed by performing spot weld of two steel sheets, respectively having sheet thickness of tand t, and nugget diameter formed by spot welding is equal to or more than 3√{(t+t)/2} (units of nugget diameter, t, and tare all mm). Curvature radius of both end parts in a radial direction of the nugget in a plate thickness direction cross surface is equal to or more than 0.3(t+t).

    Abstract: PROBLEM TO BE SOLVED: To prevent a seal material from peeling even if dissimilar metals are friction stir welded to each other.SOLUTION: A dissimilar material joined structure is provided in which an extension part of a front sub-frame is formed by laminating two steel sheets 206a, 206b, a flange part 204a of the front sub-frame and a flange part 40 of a rear sub-frame 14 of aluminum are overlapped and are friction stir welded to each other while a seal material 58 is applied onto the overlapped surface. Among two steel sheets 206a, 206b, the steel sheet 206a bonded to the rear sub-frame 14 of aluminum, includes at the end of the steel sheet 206a, a folded part 220 formed by folding the steel sheet 206a, and includes on the folded part 220 side, a long extension part 222 which is extended to the exterior further than the rear sub-frame 14. The extension part 222 is coated with the seal material 58.
