To provide a method for inspecting a welded part, capable of specifying an unwelded part in a welded part.SOLUTION: A method for inspecting a welded part comprises: a step of heating a welded part 48 between a resin-coated steel sheet 20 provided on a lower layer side and a resin-based waterproof sheet 30 provided on an upper layer side from the upper layer side in a waterproof layer provided in a building by a hot air gun 100 so that the resin-coated steel sheet 20 on the lower layer side and the waterproof sheet 30 on the upper layer side do not melt; and a step of determining a portion (raised part 60) of the welded part 48 that is raised from the state before the heating as an unwelded part.SELECTED DRAWING: Figure 4
【課題】溶着部において未溶着部を特定可能な溶着部の検査方法を提供する。【解決手段】溶着部の検査方法は、建物に設けられた防水層において、下層側に設けられた樹脂被膜鋼板２０と上層側に設けられた樹脂製の防水シート３０との溶着部４８を、下層側の樹脂被膜鋼板２０及び上層側の防水シート３０が溶融しない範囲で、熱風ガン１００によって上層側から加熱する工程と、溶着部４８において加熱前の状態よりも隆起された部分（隆起部６０）を未溶着部として判定する工程と、を有する。【選択図】図４
