  • Hybrid tubular wire electrode for submerged arc welding
    Patent number: 7763822
    Abstract: The hybrid wire of the present invention comprises approximately 1% Wt to 30% Wt of non-metallic ingredients, with the preferred concentrations selected from the range from about 5% Wt to about 15% Wt. Non-metallic compounds and metallic oxides, which were added to the tubular wires and found to perform well in the SAW process, are CaO, MgO, MgAl, K2O, CaF2, MnO, NaAlF6, and K2AlF6. Adding one or more of the listed compounds to the core composition of the tubular wires leads to an improvement of the welding performance in a SAW process due to the properties of core of the wire, while reducing the importance of the granular flux.
