A weld wire of the present invention comprises a steel sheath encapsulating a fluxed core having a combination of fluxing compounds and alloying elements. The fluxing compounds comprise up to 2%Wt of fluoride compounds and up to 49%Wt of oxide compounds. The alloying elements comprise Mn, Ni, Co, Ti and up to about 0.98%Wt of C. The amount of Co is sufficient to produce a ferrite-bainite weld metal morphology of a resulting weld. A yield strength of the resulting weld was measured from about 95 ksi to about 111 ksi.
