ABSTRACT:
A cored electrode for gas shielded arc welding to deposit a weld metal bead, where the electrode has a core of fill material surrounded by a ferrous tube with the fill material having alloying agents and oxide fluxing ingredients including, by weight of fill material, 40-60% titanium dioxide, 0.3-0.5% boron oxide, and 1.0-5.0% aluminum powder, with the aluminum powder having a higher affinity for oxygen than the oxide fluxing ingredients and with the amount of aluminum powder selected to produce 0.02-0.08% titanium, less than 0.002% boron and less than 0.10% aluminum in the weld metal.
