Abstract
A method for roll-forming a tubular member is provided. The method includes providing a roll-forming machine having a pair of rollers and a forming roller adjacent the pair of rollers. Further, cutting a strip of sheet metal to form a segment having free leading and trailing ends extending between a predetermined length; feeding the segment between the pair rollers; calculating the thickness of the segment via feedback from the pair of rollers; automatically adjusting the position of the forming roller in response to the determined thickness of the segment; advancing the segment between the pair of rollers and against the forming roller to form an annulus; and forming a weld joint between the free ends.
