Which is the shear strength of a weld metal?
Rn= 0.75×fw×0.707 ×a ×Lwi.e., factor = 0.75 fw= shear strength of the weld metal is a function of the electrode used in the SMAW process. - The tensile strength of the weld electrode can be 60, 70, 80, 90, 100, 110, or 120 ksi. - The corresponding electrodes are specified using the nomenclature E60XX, E70XX, E80XX, and so on.See all results for this questionWhere are structural welded connections usually carried out?Most structural welded connections are carried out in the fabrication factory, and are described as either butt welds or fillet welds. Site welding is also feasible, and guidance on the considerations for site welding is available in GN 7.01 .See all results for this questionWhat kind of pipe does arc welding use?Submerged arc welding pipe, SAW pipes SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available. Submerged arc welding (SAW) is a common arc welding process.See all results for this question
What are the benefits of submerged arc welding?
Foremost among these is the submerged arc welding (SAW), In this process, the end of the electrode and the arc are submerged in a granular flux that melts and forms a gaseous shield. There is more penetration into the base metal than with shielded metal arc welding, and higher strength results.See all results for this questionWelding Position - an overview | ScienceDirect Topics126.96.36.199 Submerged Arc Welding. Submerged arc welding (SAW) is a welding process in which the molten weld and the arc zone are protected from atmospheric contamination under a fusible flux. The process is normally limited to a horizontal-fillet welding position, but with a high deposition rate. This welding process is usually applied to carbon steels, low alloy steels, stainless steels, and nickel Welding - SteelConstruction.infoSubmerged arc welding (SAW), process 121 [ top ] Drawn arc stud welding, process 783 Composite bridges require the welding of shear stud connectors to the top flange of plate or box girders and other locations where steel to concrete composite action is required, e.g. at integral abutments .Some results are removed in response to a notice of local law requirement.

A Continues solid filler wire is fed from the outside. The pipe is welded first inside and then from the outside. In the case of double seam saw pipe first two halves are joined by tack weld which is called fit-up. Double seam saw pipe is havening a two weld seam opposite to each other.

Where does the hydrogen come from during welding? One source is from contaminants on the base material. Paint, oil, primer, mill scale and rust on the surface of the steel are all potential sources of hydrocarbons. They can produce hydrogen from chemical reactions as they are consumed in the heat of the welding arc and, thus, introduce hydrogen into the weld metal. Therefore, the material needs to be as clean as possible.
