Patents by Inventor Matthew Jay James

Matthew Jay James 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).

  • Stick electrode
    Patent number: 10279435
    Abstract: The exposed metal tip of the strike end of an SMAW welding electrode is covered with a protective coating formed from a binder and metal particles. Because metal particles rather than graphite particles are used to provide electrical conductivity to this protective coating, flare-up of the arc when initially struck is eliminated substantially completely. In addition, the potential for weld porosity problems is also eliminated, because the metal particles of the inventive electrode do not produce CO2 as a reaction by-product which can ultimately lead to improper welding technique.
    Type: Grant
    Filed: May 18, 2015
    Date of Patent: May 7, 2019
    Assignee: LINCOLN GLOBAL, INC.
    Inventors: Joseph Kenneth Zalokar, Matthew Jay James, David Christopher Fedor, Janet Michelle Morse

  • Welding flux
    Patent number: 7678203
    Abstract: A welding flux formulated for pipe welding or one-side welding applications including a gas releasing agent, a high melting compound and a low melting compound. The welding flux is particularly formulated for limited pass welding applications which exhibit high impact strength, good slag detachability, low weld metal hydrogen and nitrogen absorption, and facilitates in the formation of smooth and consistent weld beads.

  • Method for testing undercut on the inner diameter of pipe welds
    Patent number: 7405377
    Abstract: A method and apparatus of comparing two or more welding flux systems to determine which flux system results in the smallest incidence of undercut about a weld bead in an inner diameter of a pipe.
