Abstract
PURPOSE: To considerably stabilize the strength of a joining part by forming an annular body of an elliptical shape wherein a cut prt is located in the position intersecting roughly orthogonally with a long diameter, and subjecting both cut end faces to flash butt melt-sticking.
CONSTITUTION: A long-sized flat bar is formed to an elliptical coil shape by a coiling machine using a mandrel of an elliptical shape in section. Next, this is cut by saw-teeth in the position where a cut part S intersects orthogonally with the long diameter (a) of the ellipse, and is separated to annular boides of every one coil. Both end faces in the cut part of this annular body are butted and are welded by a flash butt welding machine.
