  • Dual wire welding or additive manufacturing contact tip and diffuser
    Patent number: 11484960
    Abstract: A welding or additive manufacturing contact tip includes an electrically-conductive body extending from a proximal end of the body to a distal end of the body. The body forms a first bore terminating at a first exit orifice at a distal end face of the body, and a second bore terminating at a second exit orifice at the distal end face of the body. The first and second exit orifices are separated from each other by a distance configured to facilitate formation of a bridge droplet between a first wire electrode delivered through the first bore and a second wire electrode delivered through the second bore during a deposition operation.
    Type: Grant
    Filed: October 21, 2019
    Date of Patent: November 1, 2022
    Assignee: Lincoln Global, Inc.
    Inventors: Alexander J. Stergios, Steven R. Peters, Bruce J. Chantry, Matthew A. Weeks
  • Dual wire welding or additive manufacturing system and method
    Patent number: 11440121
    Abstract: A system and method of welding or additive manufacturing is provided where at least two welding electrodes are provided to and passed through a two separate orifices on a single contact tip and a welding waveform is provided to the electrodes through the contact tip to weld simultaneously with both electrodes, where a bridge droplet is formed between the electrodes and then transferred to the puddle.
