徴とする溶接管の製造装置。 A welded pipe manufacturing apparatus comprising a forming roll group for continuously forming a metal strip into a cylindrical shape, and a welding means for butt welding a joint of the cylindrical metal band formed by the forming roll group, wherein the forming roll group The upstream stand group in the center is a breakdown stand group consisting of a pair of upper and lower horizontal rolls, and the remaining downstream stand group is a cage roll forming stand group consisting of a large number of small rolls. The lower roll of the horizontal roll of at least one stand in the stand group is a divided roll divided into two or more in the longitudinal direction of its rotation axis, and the two outermost rolls of the divided rolls are divided into two or more rolls whose rotation axis is parallel to the movement of the metal strip. Provided so that the plane is inclined at a certain inclination angle with respect to the direction perpendicular to the direction of movement of the metal band, and intersects the width direction of the metal band at a certain angle in the plane perpendicular to the plane of movement of the metal band. The welded pipe manufacturing apparatus is characterized in that either or both of the inclination angle and the crossing angle can be variably adjusted.
