Patent number: 11529697Abstract: The disclosed technology generally relates to consumable electrode wires and more particularly to consumable electrode wires having a core-shell structure, where the core comprises aluminum. In one aspect, a welding wire comprises a sheath having a steel composition and a core surrounded by the sheath. The core comprises aluminum (Al) at a concentration between about 3 weight % and about 20 weight % on the basis of the total weight of the welding wire, where Al is in an elemental form or is alloyed with a different metal element. The disclosed technology also relates to welding methods and systems adapted for using the aluminum-comprising electrode wires.Type: GrantFiled: October 1, 2018Date of Patent: December 20, 2022Assignee: Lincoln Global, Inc.Inventors: Shenjia Zhang, John Benjamin Schaeffer, Badri K.

Patent number: 11084275Abstract: Embodiments of additive manufacturing systems are disclosed. In one embodiment, an additive manufacturing system includes an array of multiple electrodes for sequentially depositing material layer-by-layer to form a three-dimensional (3D) part. The system includes a power source to provide electrical power for establishing a welding arc for each electrode. The system includes a drive roll to drive each electrode. The system also includes a controller to operate the system at a first deposition rate to form first resolution contour portions of a layer of the part. The controller also operates the system at a second deposition rate to form second resolution fill portions of the layer of the part. The system provides variable width deposition at the second deposition rate using a variable number of the electrodes. The first deposition rate is lower than the second deposition rate, and the first resolution is higher than the second resolution.Type: GrantFiled: May 5, 2017Date of Patent: August 10, 2021Assignee: LINCOLN GLOBAL, INC.Inventors: Badri K. Narayanan, Michael Kottman

Patent number: 10875125Abstract: Embodiments of systems and methods for characterizing weldments are disclosed. One embodiment includes a method of generating an algorithm for classifying weldments as meeting or not meeting a specification. Training data is read by a machine learning system. The training data includes cross-sectional images of training weldments, truth data indicating whether the training weldments meet the specification or not, and training weld data associated with creating the training weldments. The machine learning system trains up an algorithm using the training data such that the resultant algorithm can classify a subsequent test weldment as meeting the specification or not meeting the specification when a cross-sectional image of the test weldment and test weld data used to create the test weldment are read and processed by the classification algorithm as trained.Type: GrantFiled: June 20, 2017Date of Patent: December 29, 2020Assignee: LINCOLN GLOBAL, INC.Inventors: Badri K. Narayanan, John R. Procario, Michael A. Kottman

Patent number: 10705024Abstract: Embodiments of the present invention are directed to systems and methods of predicted a welding property for a given welding operation using at least one electrode. Embodiments determine a predicted weld deposit property and compare the predicted property to a desired property to determine whether or not a selected electrode for the given welding operation can achieve the desired weld deposit.Type: GrantFiled: March 17, 2017Date of Patent: July 7, 2020Assignee: LINCOLN GLOBAL, INC.Inventors: Badri Narayanan, John Procario, Michael Kottman
