Selecting Submerged Arc Fluxes for Carbon and Low Alloy Steels

Abstract

The submerged arc welding process has long been recognized for its versatility and excellent economics. It operates well at low or high currents, using single or multiple electrodes on plate from thin gage to unlimited thickness. The real key to this performance versatility is the flux itself-it blankets the arc, eliminates flash, spatter and smoke, controls arc stability, governs bead shape, and influences weld chemistry.
