method involved the appliion of submerged arc welding flux. Flux was packed in a grooved copper plate and a joint was fixed on top of that plate. Cut-wire particles were then inserted into the joint gap. The amount of the cut-wire particles should be enough to fill the gap up to protect the backing strip. The filler wire of the GMAW

Submerged arc welding generally uses solid welding wire, which is produced by drawing through hot-rolled wire. The main function of submerged arc welding wire is to fill the weld with metal. For example, when submerged arc welding is used for welding stainless steel, stainless steel submerged arc welding wire with the same composition as the base metal should be used.
SAW—Submerged Arc Welding welds a joint using an electric arc smothered under a bed of flux. This process, mostly automated, uses a slowly fed filler wire fed along the joint beneath the flux.; High quality welds are yielded thanks to the flux coating the arc and wire; the …
Submerged or Sub Arc Welding is a common arc welding process. It is considered as an ideal welding method to weld metal pieces especially during fabriion of street poles. The process involves heating the area by using metal electrode(s) and the work by using an arc or arcs.

Twin wire submerged arc welding (SAW) is widely used in the joining of oil or gas pipelines because of its high productivity. However, when it is applied to join the high strength steel pipe, the heat affected zone (HAZ), especially the coarse grain zone, becomes very brittle.

There are many types of welding we use to join metals together, some modern and some ancient in their creation. From forge welding with hammers in the Middle Ages, to the discovery of carbon arc welding in the 1800s, up to today’s more contemporary types of welding, such as arc welding, resistance welding, solid state welding, and stud welding, there have been many advances in the field.

2 Submerged arc welding. The submerged arc welding process is similar to the gas metal arc welding process except the arc is struck under a blanket of granular flux, hence the name submerged arc welding. The filler metal is a continuously-fed wire electrode like GMAW and FCAW.
Submerged arc welding requires more thorough edge preparation and better fit-up than shielded metal arc welding. This is because in SAW a large molten metal pool is formed so if the fit-up is poor, the molten metal and slag may run out through gaps, thus affecting the weld quality.
The modern submerged arc welding (SAW) is an arc welding process, in which one or more arc(s), formed between one or more bare wire electrodes and the work piece, provides the heat for the coalescence. In submerged arc welding, shielding of the weld arc is done using a granular flux which is fed into the weld zone using a hopper.
Esab has developed a method of cladding using these alloys, particularly for heavy-walled components. According to group product manager Jørgen Strøerg, strip-cladding, using submerged arc welding (SAW) or electroslag welding (ESW), is excellent for large areas due to the high productivity and low dilution of the base materials.
