Abstract

PURPOSE: To weld the flange and pipe easily in sound state, by making the inside diameter of uninserted part of the pipe slightly smaller than the outside diameter of the pipe at the flange interior surface, when welding the flange to the pipe.
CONSTITUTION: When welding a flange 5 to a pipe 7, the diameter of the part 6 of the pipe 7 not inserted is made slightly, about 0.5W1.0mm, smaller than the outside diameter of the pipe 7 in the flange interior surface 1. With the end part 8 of the pipe 7 abutting against the smaller end 6 of the flange interior surface, the smaller end 6 and the pipe end part 8 are welded by using a filler rod to weld the flange 5 to the pipe 7. Or, in the state mentioned above, welding is performed by placing a filler rod 12 formed in ring in the welding part. In order to prevent deformation of a flange seat surface 9, the position of the pipe end part 8 may be easily determined to maintain the specified dimension of the uninserted part. Also, the setting of the squareness of the flange seat surface 9 with respect to the axial center of the pipe may be extremely easy.
