To provide a friction stir welding device which can determine compatibility or incompatibility of the welding quality on the basis of depth information, width information and burr height information of a welding bead part immediately after friction-stir-welding a welding object member.SOLUTION: There is provided a friction stir welding device configured to: insert a welding tool attached to a main shaft to a target depth in a welding object member while rotating it at a target rotation speed to soften an insertion part of the welding object member and the vicinity thereof; advance the welding tool from a friction stir welding starting end part to a friction stir welding terminal part to linearly friction-stir-weld the welding object member; and determine welding quality indicating compatibility or incompatibility of a welding state of a welding bead part indicating a friction stir welded portion in a welding line of the welding object member being a contact part of a first welding object member and a second welding object member immediately after friction-stir-welding the welding object member in a process of advancing the welding tool.SELECTED DRAWING: Figure 4 【課題】被接合部材を摩擦攪拌接合した直後に接合ビード部の深さ情報と幅情報、及びバリ高さ情報に基づいて接合品質の適合または不適合を判定可能な摩擦攪拌接合装置を提供する。【解決手段】主軸に取り付けられた接合ツールを目標回転速度で回転させながら被接合部材に目標深度まで挿入し、前記被接合部材の挿入部及びその近傍を軟化させて摩擦攪拌接合始端部から摩擦攪拌接合終端部まで前記接合ツールを進行させて前記被接合部材を線形に摩擦攪拌接合する摩擦攪拌接合装置であって、前記接合ツールを進行する過程で、前記被接合部材を摩擦攪拌接合した直後に、第一の被接合部材と第二の被接合部材との突合せ部である前記被接合部材の接合線において摩擦攪拌接合した部位を示す接合ビード部の接合状態の適合または不適合を示す接合品質の判定を行うことを特徴とする。【選択図】 図４
