The process consists of one forming and three welding lines.Welding Equipment and Consumables for Pipe Mill The feed angle depends on strip width and final outside diameter. From there, the pipe is formed into the proper diameter and tack welded via a large-wire gas-metal-arc-welding (GMAW) process and cut in lengths from 40 to 80 feet. The second step of the welding process sends the tack-welded pipe into one of three final welding stations.

Carbon Steel Pipe | Omega Steel

Double Submerged Arc Weld (DSAW) The double submerged arc weld (DSAW) process is similar to that of the ERW process in that coils of carbon steel are unrolled in a continuous ribbon. As the DSAW method of manufacturing is typically used for larger diameter pipe, the method of roll forming the skelp is similar to but not exactly like that of ERW.Carbon Steel Pipe | Omega SteelThe spiral weld process also allows the mill to roll a much wider range of sizes than DSAW or ERW mills. Also, due to its axial symmetry, spiral weld carbon steel pipe has an inherent ability to maintain straightness.
