What is a Double Submerged Arc Weld (DSAW)? - Definition

Oct 31,2018 API spiral submerged arc welding Pipeline#0183;Double submerged arc welding is advantageous over other pipe seam welding processes such as electric resistance welding because it can be used to form large diameter (4 inches and larger) and thick (1/4 inch and up) pipe.What Is Submerged Arc Weldied?-Welded Steel Pipe-HavtonFlux refers to a material that can thaw the formed slag and gas when welding,and has the protection and metallurgical treatment to melt metals.The wire is the material that as a filler metal or as a conductive wire for welding.The main feature of submerged arc welded is that the weld and the arc area is protected from environmental Spiral submerged arc welding (SSAW) steel pipes ASTM As we know,seamless steel pipe always is small dimension,longitudinal submerge arc weld steel pipe is large dimension,but for larger dimension,we should use the method of spiral submerge arc welding instead of longitudinal submerge arc welding.With this method,we can use narrow width steel plates to produce large dimension pipes.The outside diameter is determined by the angle of the de-coiled

Spiral seam submerged arc welded steel pipe

Introduction of commonly used steel pipes-spiral seam submerged arc welded steel pipe The strip steel is bent into a spiral shape,and the inner and outer seams are welded by automatic submerged arc welding to make spiral seam steel pipe.It can be widely used in the production of large diameter steel pipes due to the following reasons 1) As long as the forming angle is changed,steel pipes of Spiral Steel Pipe Submerged Arc Welding Process and Spiral Automatic submerged arc welding was invented in 1940,a new kind of welding method,it adopts slag protection as manual welding,but is not coated electrode,the slag is specially welding flux smelting.This coating system is composed of a funnel with welding flux through a pipeline to the front of the welding.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextSpiral seam submerged arc welded steel pipeIntroduction of commonly used steel pipes-spiral seam submerged arc welded steel pipe The strip steel is bent into a spiral shape,and the inner and outer seams are welded by automatic submerged arc welding to make spiral seam steel pipe.It can be widely used in the production of large diameter steel pipes due to the following reasons 1) As long as the forming angle is changed,steel pipes of
