Submerged Arc Welding (SAW)

In submerged arc welding, or SAW, the heat for coalescence is provided by an electric arc struck between the workpiece and the consumable electrode.  Shielding is provided by a blanket of granular flux, deposited over the area to be welded.

Process Characteristics

Uses a consumable wire-fed electrode
Is shielded by a granular flux that partially vaporizes
Has a slag deposit on the weld bead
Is capable of high welding speeds and deposition rates
Produces high quality welds on thick workpieces
