  • LOW MANGANESE WELDING ELECTRODES
    Publication number: 20160236302
    Abstract: Flux cored welding electrodes comprise a iron based metal sheath and either a flux or metal core within the sheath, enclosing core ingredients. The core ingredients and sheath together comprise, in weight percentages based on the total weight of the electrode, very low levels of manganese. While having low levels of manganese the electrodes satisfy the strength and safety requirements required of commercial electrodes. Embodiments contain manganese in the range of 0.09 to 0.19% by weight of the electrode, along with other components.

  • HIGH FRACTURE TOUGHNESS WELDS IN THICK WORKPIECES
    Publication number: 20150034605
    Abstract: Embodiments of flux cored welding electrodes and methods of use thereof are disclosed. The flux cored welding electrodes limit brittleness of flux cored arc welds, particularly in thick weld deposits. Limiting brittleness in thick (e.g., from about 1? to about 6?) flux cored arc welds is achieved by utilizing flux cored welding electrodes having chemical compositions that reduce (as compared to presently marketed electrodes) or altogether eliminate niobium and vanadium from their chemical compositions.

  • Feeding lubricant for cored welding electrode
    Patent number: 8395071
    Abstract: A feeding lubricant for use on a welding electrode comprises about 10 to 40 wt. % of at least one soap-based lubricant, about 40 to 90 wt. % of at least one solid particulate lubricant selected from MoS2, WS2, ZnO, graphite and PTFE and up to 20 wt. % of at least one optional additional particulate lubricant ingredient.
