  • Low manganese fume welding process
    Patent number: 10766091
    Abstract: The amount of manganese in the weld fumes generated by an arc welding process can be reduced without reducing the concentration of manganese in the weld deposit ultimately obtained by supplying the manganese to the weld site by the hot wire welding electrode of a hot wire welding process.
    Type: Grant
    Filed: April 27, 2015
    Date of Patent: September 8, 2020
    Assignee: LINCOLN GLOBAL, INC.
    Inventor: J. Ben Schaeffer

  • Welding wire with perovskite coating
    Patent number: 8952295
    Abstract: The electrical resistance between a welding wire used for arc welding and the welding gun contact tip through which it passes is reduced by providing on the surfaces of the welding wire a solid conductor comprising an electrically conductive perovskite or other thermally stable, electrically conductive particulate solid.
    Type: Grant
    Filed: June 18, 2008
    Date of Patent: February 10, 2015
    Assignee: Lincoln Global, Inc.
    Inventors: J. Ben Schaeffer, Shitong Cao, Joel D. Kneisley, Badri K. Narayanan
  • Welding wire for submerged arc welding
    Patent number: 8901455
    Abstract: The copper cladding normally applied to the surfaces of a submerged arc welding wire for preventing weld gun contact tip abrasive wear is replaced with a solid lubricant. This eliminates copper contamination of the weld from the copper cladding while preserving the useful life of the contact tip.
    Type: Grant

    Date of Patent: December 2, 2014
    Assignee: Lincoln Global, Inc.
    Inventors: J. Ben Schaeffer, Boris Kahn
  • WELDING WIRE FOR SUBMERGED ARC WELDING
    Publication number: 20090314756
    Abstract: The copper cladding normally applied to the surfaces of a submerged arc welding wire for preventing weld gun contact tip abrasive wear is replaced with a solid lubricant. This eliminates copper contamination of the weld from the copper cladding while preserving the useful life of the contact tip.
