Sub arc welding is a process in which the welding actually occurs while submerged under a layer of flux. Not only does this prevent oxygen from entering the weld and thus porosity, but it also keeps the dangerous arc from sputtering and spattering from the weld.

submerged arc welding (SAW)

saw stands for suberged arc welding, where the weld is submerged underneath the flux

Submerged arc welding is called "submerged" because the high voltage electrical current (called the "arc") that heats the metal and wire to weld together is submerged underneath layers of granular earth materials called "flux". About 50% to 90% of this flux can be re-used and fed back into the system with the proper equipment.

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.

No. Double Submerged Arc Welded is DSAW; LSAW stands for Longitudinal Submerged Arc Welded. As an aside, HSAW stands for Helically Submerged Arc Welded. All of these refer to various types of pipe manufacturing processes.

Forge welding and resistance welding were the 1st. Sheet metal arc, gas metal arc, submerged arc, electroslag, flux-cored arc, laser beam, and elctrobeam followed later.

same as regular SAW but with an extra wire input

The heat input in the case of Submerged Arc Welding (SAW) is higher than that in manual welding process. Reason is that the welding proceeds continuously while the work is rotated. In manual welding, it is controlled by the welder besides the time gap for changeover of electrode, relaxation by operator etc.

Double Sub-merged Arc Welding usually associated with spiral welded pipe. The welding arc is submerged in flux to protect from air impurities, this process is done on both the id and od seperately hence double submerged.

INCONEL alloy 600 is readily joined by conventional welding processes. Welding materials for joining alloy 600 are INCONEL Welding Electrode 182 for shielded metal-arc welding*, INCONEL Filler Metal 82 for gas tungsten-arc and gas metal-arc welding, and INCONEL Filler Metal 82 and INCOFLUX 4 Submerged Arc Flux for the submerged-arc process. Welds made with INCONEL Welding Electrode 182 may have decreased ductility after extended exposure to temperatures of 1000° to 1400°F (540° to 760°).

The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.

If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.

the purpose of the arc welding is joining two metals

Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.

Yes, arc welding does create ozone. It is because the temperatures created during arc welding convert the nearby oxygen to ozone.

Arc welding uses an electrical current to create enough heat to melt metal. Any type of welding that uses an electric arc is technically arc welding. However, most people use the term 'arc welding' to mean shielded metal arc welding (SMAW), or 'stick welding'. SMAW, MIG, and flux core wire welding use the filler metal as both electrode and filler; TIG welding uses an electric arc to heat the base metal and a separate filler rod to add metal to the weld.

smaw welding is sheilded metal arc welding

This acronym means Helical Submerged Arc Welded pipes. They are also know as Spiral Submerged Arc Welded pipes. These specification of pipes are assembled via welding. They are mainly deployed for the transportation of oil and gas in some cases, water. Hope this helps.

Submerged arc welding uses a wire electrode (like MIG welding) and a granular flux to protect the puddle and add alloys to the weld. This flux is deposited into the weld area by a hopper/tube arrangement which relies on gravity. The operator cannot see the weld taking place and relies on gauges to ensure the process is proceeding correctly. This process can only be done in the flat position. On the positive side a large amount of weld is deposited compared to any other process. This process can be manual, semi or fully automated. In MIG welding (Inert Gas Shielded Arc Welding) the protective shield is an inert gas which allows the operator to see the weld as it takes place. It can also be manual, semi or fully automated.

Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.

ARC welding uses large amounts of electricity to melt the metal, not a hot flame. So no, LPG cannot be used for ARC welding.
