Gas shielded arc welding method and steel pipe manufacturing method
Provided is a gas-shielded arc welding method in which the number of seams, which are portions where defects are likely to occur, is small, and in which automatic welding can be performed by a welding robot. A gas-shielded arc welding method for welding a steel pipe (Wo) by multilayer build-up welding comprises the steps of: fixing a groove part (10) of the steel pipe (Wo) by mounting a steel frame on a mounting tool (12) provided on the steel pipe (Wo) and erecting an adjustment jig (13); a step of welding the groove part (10) to the first one or several layers by semi-automatic welding or manual welding; removing the steel frame to erect the adjusting clamp (13) after the welding of the first layer or several layers is finished; and a step in which the remaining layer is welded by a welding robot (100) so that the weld bead seam is two or less.
本发明提供作为容易产生缺陷的部分的接缝的数量较少、并且能够由焊接机器人进行自动焊接的气体保护电弧焊接方法。通过多层堆焊而焊接钢管(Wo)的气体保护电弧焊接方法包括：在设置于钢管(Wo)的安装件(12)装配钢架架设调整夹具(13)而固定钢管(Wo)的坡口部(10)的步骤；对坡口部(10)通过半自动焊接或手动焊接而焊接到最初的一层或几层的步骤；在到最初的一层或几层的焊接结束后撤去钢架架设调整夹具(13)的步骤；以及利用焊接机器人(100)以使焊道接缝成为两处以下的方式焊接剩余的层的步骤。
