Abstract
A metallic strip having at least one surface enhanced with a texture pattern is formed into a welded tube. A fin insert shapes the edges of the metallic strip prior to welding and minimizes the formation of a protruding weld bead. The longitudinally running edges of the metallic strip adjacent to the enhancement are angled so that the unenhanced portions of the strip edges contact during welding. By having the unenhanced portions contact, fluctuations in metal volume during welding are reduced. This reduces weld instability.
