Patents by Inventor Tre' Dorell Heflin-King

Tre' Dorell Heflin-King has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11052493
    Abstract: The invention relates generally to welding and, more specifically, to corrosion resistant weld deposits created during arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). A disclosed corrosion resistant weld deposit comprises nickel, chromium, and copper, and has a low porosity.
    Type: Grant
    Filed: October 30, 2018
    Date of Patent: July 6, 2021
    Assignee: HOBART BROTHERS LLC
    Inventors: Mario Anthony Amata, Steven Edward Barhorst, Tre′ Dorell Heflin-King
  • Publication number: 20200164455
    Abstract: A welding system includes a welding power source configured to provide pulsed electropositive direct current (DCEP), a gas supply system configured to provide a shielding gas flow that is at least 90% argon (Ar), a welding wire feeder configured to provide tubular welding wire. The DCEP, the tubular welding wire, and the shielding gas flow are combined to form a weld deposit on a zinc-coated workpiece, wherein less than approximately 10 wt % of the tubular welding wire is converted to spatter while forming the weld deposit on the zinc-coated workpiece.
    Type: Application

  • Patent number: 10427250
    Abstract: This disclosure relates generally to welding and, more specifically, to electrodes for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW) of zinc-coated workpieces. In an embodiment, a welding consumable for welding a zinc-coated steel workpiece includes a zinc (Zn) content between approximately 0.01 wt % and approximately 4 wt %, based on the weight of the welding consumable. It is presently recognized that intentionally including Zn in welding wires for welding galvanized workpieces unexpectedly and counterintuitively alleviates spatter and porosity problems that are caused by the Zn coating of the galvanized workpieces.

  • Patent number: 10112268
    Abstract: The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). A disclosed tubular welding wire has a sheath and a core, and the tubular welding wire includes an organic stabilizer component, a rare earth component, and a corrosion resistant component comprising one or more of: nickel, chromium, and copper.
