This desire made it necessary to find out optimum parameters for SAW of HY-100 steel.Which is more efficient submerged or submerged arc welding?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 an alloy steel, a multi-pass procedure is normally necessary.See all results for this question

    Jan 09, 1993 · 9.4.2 Submerged arc welding Submerged arc welding (SAW) is an attractive process for larger pipes, vessels and heavier wall thickness components in general. Practical experience is generally good, although nitrogen-induced porosity and transverse and longitudinal cracks have been observed. 7 These cracks are not always easy to observe on X-ray films and can be the source of MechanizationJan 03, 2018Microextraction MethodJan 09, 2011Cylindrical TubeJan 02, 2011Molten Weld Pool - an overview | ScienceDirect TopicsJan 09, 1993See more resultsSubmerged Arc Welding - ESAB75 % for MMA welding. Submerged arc welding can be performed using either DC or AC. 1.2 Applications Submerged arc welding can be employed for an extremely wide range of workpieces.
