To provide a vehicle body panel joining structure formed of aluminum alloy that has a stable joining strength, and a vehicle body panel joining method.SOLUTION: A vehicle body panel joining structure has a roof panel 10 formed of aluminum alloy, and a roof side rail 11 formed of aluminum alloy, the roof panel and the roof side rail being welded using a filler material of aluminum alloy. The tensile strength of the filler material is set to be higher than the tensile strength of the member that has a lower tensile strength in the base material of the roof panel 10 and the base material of the roof side rail 11. A throat thickness (a) of a welding metal portion 20 including the filler material and leg lengths (b) and (c) thereof are equal to or greater than the plate thickness of the base material that has a thin plate thickness in the base material of the roof panel 10 and the base material of the roof side rail 11.SELECTED DRAWING: Figure 3

    【課題】安定した接合強度を有するアルミニウム合金製の車体パネルの接合構造、および車体パネルの接合方法を提供する。【解決手段】車体パネルの接合構造は、アルミニウム合金製のルーフパネル10とアルミニウム合金製のルーフサイドレール11とを、アルミニウム合金の溶加材を用いて溶接する車体パネルの接合構造において、溶加材の引張強度は、ルーフパネル10の母材およびルーフサイドレール11の母材のうち引張強度が低い部材の引張強度より高く設定し、溶加材を含む溶接金属部20ののど厚aおよび脚長b,cは、ルーフパネル10の母材およびルーフサイドレール11の母材のうち板厚が薄い母材の板厚以上である。【選択図】図3
