Abstract

A method of production of welded tube of various dimensions in which a sheet of material is deformed by start and finish roll assemblies to a cross section having upper edge arcs, side cheek arcs and base apex arcs with a slit which can then be welded. The resultant pipe has the radii and lengths of the edge axes (a) and apex arcs (c) held constant and only the lengths or radii of the side cheek axes (6) varied for the production of tubes of various calibres. The wide strip of material is formed such the side cheek arc radii are first formed onto the edge arcs (a) and the apex arcs (c) of constant radius are produced.
