Welded pipes are metal products that start as a strip that would be roll-formed and then welded to form a tube.
The concept of spiral-welded pipe fabrication is the twisting of a metal strip into a spiral shape, followed by welding where the edges join one another to form a seam. This fabrication method starts from a steel coil. The flat and uncoiled steel sheet, after edge trimming for welding preparation, passes through a triplet of rollers positioned in a "pyramid" configuration, and oriented at an appropriate angle with respect to the de-coiling direction. In such a way, the steel coil is bent into a spiral shape. There are two welding stations just after passing through the pyramid rollers, one internal and one external, which perform pipe welding with the submerged arc welding method. In SAW, the metal is joined by fusing with an electric arc that develops between a metal electrode and the edge of the pipe. A layer of granular, fusible material covers the weld area and protects the arc and the molten metal. Internal welding is performed first, followed by external welding.
