    Abstract: A metal-core weld wire usable for gas shielded arc welding gapless joints on low carbon and low alloy galvanized and galvanealed steels. The metal-core weld wire includes a low carbon steel sheath surrounding a core composition. In one embodiment, the low carbon steel sheath includes, by total weight of the metal-core weld wire, between approximately 0.01-0.03% C, and the core composition includes, by total weight of the metal-core weld wire, between approximately 0.05-0.20% Ti, between approximately 0.05-1.00% Nb, Fe powder, and Mn to the extent that the metal-core weld wire includes between approximately 0.1-1.0% Mn wherein the metal-core weld wire includes between approximately 0.1-1.0% Si. The core composition is, by total weight of the metal-core weld wire, between approximately 0.001-12.0%. The metal-core weld wire provides, at weld rates up to 150 cm/min, reduced arc ionization potential and spatter, and improved arc stability and shielding. The metal-core weld wire produces, at weld rates up to 150 cm/min, weld deposits having reduced blow holes and porosity, no liquid metal embrittlement, and reduced weld pool surface tension resulting in an improved wetting characteristic.

    Abstract: The gas-metal arc welding of metal-core wile electrodes in the pure Ar shielding gas for carbon steel, low alloy steel, and ferritic stainless steel is described. Such shielding gas provides several benefits not realized ??the gas-metal arc welding process with solid wires. When compared to standard argon/oxygen containing gas mixtures normally used for metal cored wires, these benefits include reduced silicate islands on the weld surface for improved weld appearance, reduced welding fume, and lower weld spatter, all of which provide easier clean-up after the welding operation. Benefits also include reduced arc penetration desirable for welding on thinner materials or handling poor joint fit-up. Lower voltage requirement further makes it possible to weld on thinner materials. Lower oxygen content in the weld deposits provide better toughness and easier welding in all-positions.
