What is a Double Submerged Arc Weld (DSAW)? - Definition 304 welded steel pipe Submerged arc welding
Oct 31, 2018 · Double submerged arc welding is a process that involves two submerged arc welding passes. One pass of submerged arc welding takes place on one side of the material, and another pass takes place on the opposite side of the first pass. 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.Estimated Reading Time: 2 minsWelding stainless steel right - The FabricatorNov 01, 2017 · Submerged Arc Welding .
