Abstract
PURPOSE: To eliminate the stepped zone, and to improve the roundness, by winding up a metallic blank sheet into plural spirally wound layers so as to make the winding starting edge and the winding ending edge come to the same circumferential direction, cutting the longitude of the cylinder along a line connecting the said edges, and applying a butt welding to the cut planes.
CONSTITUTION: A thin steel sheet 2 is spirally wound up into plural layers so as to make the winding starting edge 5 and the winding ending edge 4 come to almost same circumferential direction. Then the longitude of the spirally wound multilayer cylider 3 is cut along a single-dotted chain line A nearly connecting the edges 4, 5. Then, the cylinder shell 3 is pushed inward in the direction of an arrow mark D so as to butt the cut planes aWd against the cut planes b'We', and a seam welding 15 is applied to whole region of the butted planes.
