Abstract
There is provided a method for the manufacture of a welded tube having an enhanced inner wall. A fin insert shapes the edges of a metallic strip prior to welding and minimizes the formation of a weld bead inside the tube. The portion of the edge of the metallic strip adjacent the outer surface of the tube is formed to a first angle, while that portion of the edge adjacent an inner wall of the tube is formed to a second, lesser angle.
