Submerged Arc Welding - ESAB
Submerged arc welding is most efficient if the joint can be filled with as few passes as possible. If, when working in mild steel, the workpiece can be turned over, and if the material is not too thick, a bead is often applied from each side of the joint. If the basic material is alloyed steel, a multi-pass procedure is normally necessary.File Size: 2MBPage Count: 42Spiral Welded Steel Pipe Philippines | SSAW/HSAW Pipe d36 angle steel Submerged arc weldingIt is using the same welding technology of Submerged Arc-Welding with LSAW Pipes.
