    摘要： Methods for forming an aluminum weld on an aluminum work surface are disclosed. The methods include providing an aluminum metal-core wire having a sheath with an outer surface and a core composition within the sheath, applying a voltage to the aluminum metal-core wire in the vicinity of the aluminum work surface to generate an arc, and melting the wire and the work surface to form the weld. The sheath is formed with an inorganic lubricant on its outer surface and the core composition includes metal powders, metal alloy powders, or combinations thereof and less than about 5% of non-metallic components or non-metallic agents based on the weight of the wire.

    摘要： 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.
