· The flash weld that has formed is now removed from the outside diameter of the tube. Once the weld has been tested the tube then passes through a series of sizing rolls to attain its precise finished size, after which the tube is then straightened and cut to length. The material used in the manufacturing process is typically SAE 1010.

Each hot round is fed into a set of rolls having crossed axes and surface contours that pull it through the rolls, thus rupturing it longitudinally. The force of the rolls then causes the metal to flow around a piercing point, enlarging the axial hole, smoothing the inside surface and forming a tube. After being pierced, the rough tube is usually hot rolled to final dimensions. b) Press ...

Increasing the Efficiency on ERW/HFI Tube Mills: Part One By Pierre Huot, Vice President, Xiris Automation Inc. Abstract: Electric resistance welding (ERW) has, for many years, been used for making longitudinal seam welds in steel line pipe, principally for use in low grade structural and water pipeline appliions. The advent of high frequency induction (HFI) techniques has led to ...
The weld roll setting adjustment is incorrect (too wide). The mill speed is excessive (too fast) for the welder. The weld rolls are worn beyond tolerance. Problem #6: Weld chatter Weld chatter results from the inability to achieve a clean cut of the outside weld bead. The scarf knife chatters and produces a ribbed, or rough, cut on the of the tube. The causes of weld chatter are ...
· They include marking of the tube, roll over, buckling, bad welds and incorrect sizing. II. Size Range of the Breakdown Rolls .
