Previous work performed with ANSI/AWS A5.5-96 E100/110/12018M manual covered electrodes and ANSI/AWS A5.29-98 E91T5-K2, E101/111T5-K3 and E120T5- K4 flux and metal cored wires, have shown that in ferritic high strength C-Mn-Ni-Mo and C-Mn-Ni-Mo-Cr systems, satisfying the required toughness was not difficult, but consistently achieving the tensile strength minimum requirements turned out to be more demanding. The objective of this work was to study the effect that variations in the alloying content (C, Mn and Cr) of ferritic deposits, of the C-Mn- 1.8%Ni- 0.5%Mo and C-Mn- 1.8%Ni-0.5%Mo-Cr systems, produced with the submerged arc welding process, have on their mechanical properties and microstructure.
