The Welding Process The welding of the spirally welded pipes is based on the Double-Sided Submerged Arc Welding (DSAW) process.The principle Arc welding works by using electric current to produce an electric arc in a gas environment.The arc's heat brings the metal to fusion point.A key question is how to increase both the concentration

Spiral Weld.The most easily distinguishable manufacturing method for carbon steel pipe is spiral weld.In this process the weld is created in the exact same manner as that of DSAW,only the weld seam takes on a helical or spiral appearance due to the way the skelp is rolled to form.China API Seamless/Welding Oil/Gas Steel Welded line Steel Pipe,Line Pipe,ERW Steel Pipe manufacturer / supplier in China,offering API Seamless/Welding Oil/Gas Steel Welded line Carbon/Alloy Pipe for Oilfield Services,Group brand Seamless/ERW welded Stainless/Carbon/Alloy welding spiral metal steel oil and gas line metal steel Square/round Steel Material for Building Material/Water Pipe/Steel Material,Good Price Hot Rolled Black Carbon Steel Solid Round Billet with SGS
Unreasonable welding heat input.The traditional view of welding heat input is that when welding duplex stainless steel with 22% chromium content,the heat input should be limited to 0.5 2.5kJ / mm,and when welding super duplex stainless steel with 25% chromium content,the heat input should be limited to 0.5 ~ 1.5kJ / mm.Differences Between ERW and EFW Steel PipeThe part of the filling metal is all from the electrode.Melt Gas Shielded Welding (GMAW)A type of electrofusion welding (EFW) that is similar to submerged arc welding,but its protection comes from inert gases and works better.Spiral welding (SSAW)this is also a type of submerged arc welding with a spiral weld.
