Abstract
A method of manufacturing an electric resistance welding pipe is provided in which a lateral edge shape is made to be an appropriate shape immediately before electric resistance welding is performed, whereby penetrators are securely removed during the electric resistance welding and, consequently, an electric resistance welding pipe having excellent characterization of welded seam can be obtained. A fin shape in finpass forming is printed to lateral edges of a strip, whereby the lateral edges of the strip are shaped with predetermined tapering.
