20130043219 | METHOD AND SYSTEM TO START AND USE COMBINATION FILLER WIRE FEED AND HIGH INTENSITY ENERGY SOURCE FOR WELDING - A method and system to weld or join workpieces employing a high intensity energy source to create a weld puddle and at least one resistive filler wire which is heated to at or near its melting temperature and deposited into the weld puddle. | 02-21-2013 |
20140008332 | METHOD AND SYSTEM OF USING GAS FLOW TO CONTROL WELD PUDDLE IN OUT-OF-POSITION WELDING - A system and method for using gas flow to control a molten puddle in out-of-position applications is provided. The system includes a high intensity energy source configured to heat at lease one workpiece to create a molten puddle and a housing assembly configured to supply a gas over the molten puddle in order to minimize sagging of the molten puddle in the out-of-position applications. The system also includes a gas source that is configured to supply the gas. The gas source is operatively connected to the housing assembly. The pressure of the gas in the housing assembly is in a range of 15 psi to 35 psi. The method includes heating at least one workpiece to create a molten puddle and supplying a gas over the molten puddle via a housing assembly in order to minimize sagging of the molten puddle in the out-of-position applications. | 01-09-2014 |
20140008339 | METHOD AND SYSTEM FOR REMOVING MATERIAL FROM A CUT-JOINT - A system and method for removing material in a workpiece is provided. The system includes a laser system that melts a portion of the workpiece by heating the workpiece. The system includes a wire feeder system that feeds a wire to the workpiece to remove molten metal from the workpiece by using the wire. The wire is configured such that the molten metal adheres to the wire when the wire makes contact with the molten metal. The melting by the laser system includes a cutting or a gouging of the workpiece. In some embodiments, the system includes a hot wire power supply that supplies heating current through a length of the wire to heat the length of the wire to a desired temperature. The heating of the wire facilitates the adherence of the molten metal to the wire. | 01-09-2014 |
20140263194 | CORED NON-ARC CONSUMABLE FOR JOINING OR OVERLAYING AND SYSTEMS AND METHODS FOR USING CORED NON-ARC CONSUMABLES - Embodiments of the invention relate to consumables that are used with non-arc deposition processes, including hot-wire deposition processes. Exemplary embodiments of the present invention eliminate the use of arc initiators or arc stabilizers in the consumable. Other embodiments add additional amounts of carbonates in the consumable than would otherwise be present in consumables for arc welding processes. Similarly, other exemplary embodiments of the present invention include additional amounts of nitrides than would otherwise be present in arc process consumables. Other exemplary embodiments include carbides that are desired to be deposited through the non-arc processes. | 09-18-2014 |
20150034605 | HIGH FRACTURE TOUGHNESS WELDS IN THICK WORKPIECES - Embodiments of flux cored welding electrodes and methods of use thereof are disclosed. The flux cored welding electrodes limit brittleness of flux cored arc welds, particularly in thick weld deposits. Limiting brittleness in thick (e.g., from about 1″ to about 6″) flux cored arc welds is achieved by utilizing flux cored welding electrodes having chemical compositions that reduce (as compared to presently marketed electrodes) or altogether eliminate niobium and vanadium from their chemical compositions. | 02-05-2015 |
