Shah, S; Blander, M; Indacochea, J E

Compositional changes of weld metal from welds made by submerged arc flux welding of steel using CaF/sub 2/-CaO-SiO/sub 2/ fluxes are consistent with an electrochemical mechanism in which the filler wire is anodically oxidized to form oxides and fluorides, and metals are cathodically deposited at the weld pool-flux interface. This speculative mechanism, if proven by further detailed studies, could make it possible to predict fluxes which will improve the quality of welds. 10 refs., 3 figs., 3 tabs.
