submergedarcarc
Submergedarcarc is not a standard term in welding literature; it most likely refers to Submerged Arc Welding (SAW). SAW is a welding process in which a continuously fed filler wire electrode is shielded by a granular flux that covers the molten weld and excludes air. The flux also forms a slag layer that protects the solidifying weld, which is why the arc and weld area appear to be submerged beneath the flux.
In SAW, the arc is struck between the electrode and the workpiece, with the weld pool protected
Equipment for SAW includes a constant-voltage power source, a wire feeder, a flux hopper and delivery tube,
Materials and applications: SAW is widely used for carbon and low-alloy steels, stainless steels, and some nickel
Advantages and limitations: SAW offers high deposition rates, deep penetration, stable arc behavior, and strong process
