PURPOSE: A method of rotary welding of a connector pipe is provided to enable rapid manufacture of connector pipes by rotating a base metal and a sub-metal perpendicular to the base metal while touching an electric welding rod to welding end in the circumference of a rotation radius of the sub-metal. CONSTITUTION: A circular flat welding surface(2a) is pressed into a welding portion of a tubular base metal(2) perpendicularly to a welding end(3a) of a sub-metal(3). The welding end(3a) of the sub-metal(3) is formed as a circular section perpendicular to a longitudinal direction. The center of the welding surface(2a) is fixed facing upward on a rotary means by a fixing means(C). The welding end(3a) is perpendicularly contacted to the welding surface(2a), and fixed by a supporting means(V). The materials(2,3) are rotated suitable for welding by a rotary means(R) while welding the welding end(3a). The circumference of a rotation radius of the sub-metal(3) constitutes a circular welding line.
