Alloy fluxes for surfacing

Abstract: Submerged arc surfacing is the most productive fusion process for surface refining. The chosen alloyed agglomerated fluxes can efficiently affect surfacing quality and productivity. They enable single-layer surfacing of selected wear-resistant and corrosion-resistant cast irons on unalloyed structural steels. With alloyed agglomerated fluxes, it is recommended to surface with a low welding current and high welding voltage. The low welding current will produce minimum melting of the substrate and minimum burnout of alloying elements. The high welding voltage, however, will produce more intense melting of the welding flux, which will increase welding efficiency and alloying of the surfacing deposit by means of the welding flux. Such setting of the welding parameters is characteristic of welding with a multiple-wire electrode.
