PROBLEM TO BE SOLVED: To provide a teaching coordinate data creation method for a seam welding device, the seam welding device and a jig for performing high-quality seam welding even to a work in which an end of a laminated flange part is not smoothly formed.SOLUTION: Distance Y from a pressure energization scheduled part Pws between roller electrodes 14a, 14b to an end of a laminated flange part 16 is adjusted within tolerance. In addition, coincidence TZ between a direction LZ of a roller electrode 14 at the pressure energization scheduled part Pws and a welding path TL on the laminated flange part 16 is adjusted. Parallelism TY between a tangential direction TD of the circumference of the roller electrode 14 at the pressure energization scheduled part Pws of the roller electrode 14 and the welding path TL on the laminated flange part 16 is adjusted. 【課題】積層フランジ部の端部が滑らかに形成されていないワークであっても、高品質のシーム溶接を施せるシーム溶接装置用の教示座標データ作成方法、シーム溶接装置及びジグを提供する。【解決手段】ローラ電極１４ａ、１４ｂ間の加圧通電予定部Ｐｗｓから積層フランジ部１６の端部までの距離Ｙを許容値内に合わせる。また、加圧通電予定部Ｐｗｓにおけるローラ電極１４の向きＬＺと積層フランジ部１６上の溶接経路ＴＬとの一致度ＴＺを合わせる。ローラ電極１４の加圧通電予定部Ｐｗｓにおけるローラ電極１４の円周の接線方向ＴＤと積層フランジ部１６上の溶接経路ＴＬとの平行度ＴＹを合わせる。【選択図】図４
