摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a UOE steel pipe, by which a transverse crack in the weld zone of the UOE steel pipe the tensile strength of which is ≥800 MPa, the outside diameter of which is ≥500 mm and also the thickness of which is ≥6 mm is prevented without being accompanied with the management of welding materials and extra pressing work.
SOLUTION: Before performing internal welding and external welding to grooved parts 2 formed in the edge parts of an open pipe 1 the tensile strength of which is ≥800 MPa and after removing scale in a prescribed region A which is continued to the grooved part 2 in the peripheral direction of the open pipe in the outside 1a and/or the inside 1b of the open pipe 1, the internal welding and the external welding are performed.
