Differences Between SAW and ERW Pipe Winsteel Group

ERW Welded Steel Pipe Manufacturing MethodWhen the ERW steel pipe welding process, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc-shaped and rotate as the material passes between them. This allows the electrodes to stay in constant contact with the material to make long continuous welds.
