  • Metal cored welding wire that produces reduced manganese fumes and method
    Patent number: 9815148
    Abstract: Various embodiments of a metal cored wires and methods are disclosed. In one embodiment of the present invention, a metal cored wire comprises a metal sheath and a metal-powder core material comprising manganese particles. The manganese particles are coated with a coating material to reduce the manganese fumes and exposure during welding.
    Type: Grant

  • Metal cored welding wire, hardband alloy and method
    Patent number: 9724786
    Abstract: Various embodiments of a metal cored wires, hardband alloys, and methods are disclosed. In one embodiment of the present invention, a hardbanding wire comprises from about from about 16% to about 30% by weight chromium; from about 4% to about 10% by weight nickel; from about 0.05% to about 0.8% by weight nitrogen; from about 1% to about 4% by weight manganese; from about 1% to about 4% by weight carbon from about 0.5% to about 5% by weight molybdenum; from about 0.25% to about 2% by weight silicon; and the remainder is iron including trace elements. The hardband alloy produced by the metal cored wire meets API magnetic permeability specifications and has improved metal to metal, adhesive wear resistance compared to conventional hardband alloys.
