Patent number: 9579751Abstract: In a stick electrode for electric arc welding having a center alloy wire and an outer cellulose coating which coating includes powdered fluxing agents, alloy powder, cellulose powder and a binder. The improvement involves forming the binder as a solution of sodium silicate and 61-78 percent by weight of the binder. The binder comprises 25-35% of the coating to produce at least about 4% by weight of water in the electrode. Furthermore, the fluxing agent is titanium dioxide with a percentage greater than 12 percent of the coating.Type: GrantFiled: February 21, 2006Date of Patent: February 28, 2017Assignee: LINCOLN GLOBAL, INC.Inventors: Randall M. Burt, Jon P. Chiappone, Craig B. Dallam, Robert J. Weaver

Patent number: 9095919Abstract: A stick electrode for depositing an high strength weld metal bead on a workpiece where the yield strength of the weld metal is between 85 ksi and 125 ksi irrespective of the cooling rate. The electrode deposits weld metal having 0.80-1.85% by weight manganese, 0.25-0.50% by weight molybdenum, 1.25-2.50% by weight nickel, and less than 0.07% by weight carbon, wherein the ratios of the carbon, manganese and molybdenum are adjusted to provide a carbon equivalent in deposited weld metal in the range of 0.17 to 0.30 and preferably less than 0.22.Type: GrantFiled: February 21, 2006Date of Patent: August 4, 2015Assignee: Lincoln Global, Inc.Inventors: Randall M.

Patent number: 7307238Abstract: A method of measuring the quality of a stick electrode used in forming the root bead of a pipe joint, which electrode has a wire diameter, a length substantially greater than 12 inches and an upper exposed rod head. The method comprises: preparing a standardized workpiece including two spaced plates with a groove between the plates having a set profile including a lower gap duplicating the root gap of the pipe joint and mounting the standardized workpiece on an incline with the groove facing upwardly where the incline is at a fixed known angle. Then a stick electrode of the type to be measured is selected and the rod head of the selected electrode is connected to the power lead of a DC power source set to a given output current correlated with the type of electrode.Type: GrantFiled: February 21, 2006Date of Patent: December 11, 2007Assignee: Lincoln Global, Inc.Inventors: Randall M.

Patent number: 7173215Abstract: Methods and systems are disclosed for characterizing a welding consumable, such as flux or an electrode, and/or for comparing two or more welding consumables for use in narrow gap deep groove welding operations, including creating test welds on fixtures having joint grooves of various angles for a given groove depth, followed by controlled standardized non-aggressive slag removal operations, and quantification of the amount of slag remaining in the groove, wherein the welding consumables are each characterized using the same fixtures, welding conditions, workpiece groove depths, groove angles, and removal operations, to construct a set of results, such as a table or rating, by which the individual welding consumables can be rated and/or a determination can be made as to which of two consumables provides superior performance with respect to ease of removal in deep groove welding operations.Type: GrantFiled: July 13, 2005Date of Patent: February 6, 2007Assignee: Lincoln Global, Inc.Inventors: Ashish Kapoor, Teresa A.
