20120213626 | EXPLOSION-WELDED GAS TURBINE SHROUD AND A PROCESS OF FORMING AN EXPLOSION-WELDED GAS TURBINE - An explosion-welded turbine shroud and a process of forming an explosion-welded gas turbine shroud are disclosed. The explosion-welded gas turbine shroud includes a first alloy explosion welded to a second alloy. In the explosion-welded gas turbine shroud, the first alloy forms at least a portion of a hot gas path or an expansion region of the gas turbine shroud includes the first alloy. The process includes explosion welding a first alloy to a second alloy to form the gas turbine shroud. | 08-23-2012 |
20130181071 | FUEL NOZZLE AND PROCESS OF FABRICATING A FUEL NOZZLE - Disclosed is a fuel nozzle and a process of fabricating a fuel nozzle. The fuel nozzle includes a fuel nozzle end cover and a fuel nozzle insert. The fuel nozzle insert is welded to the fuel nozzle end cover by a welding process selected from the group consisting of beam welding, solid state welding, and combinations thereof and/or the fuel nozzle insert includes a first fuel nozzle insert portion and a second fuel nozzle insert portion. The process includes welding the fuel nozzle insert to the fuel nozzle end cover. | 07-18-2013 |
20130205789 | FUEL NOZZLE END COVER, FUEL NOZZLE, AND PROCESS OF FABRICATING A FUEL NOZZLE END COVER - Disclosed is a fuel nozzle end cover, a fuel nozzle and a process of fabricating a fuel nozzle end cover. The fuel nozzle end cover includes a base material and one or more features extending from the base material into a cavity of the fuel nozzle end cover. The one or more features are secured to the base material by a process selected from the group consisting of beam welding, friction welding, gas tungsten arc welding, gas metal arc welding, and combinations thereof. The fuel nozzle includes a fuel nozzle insert and a fuel nozzle end cover. The process of fabricating the fuel nozzle end cover includes providing a base material and securing one or more features to the base material by a welding process selected from the group consisting of beam welding, friction welding, gas tungsten arc welding, gas metal arc welding, and combinations thereof. | 08-15-2013 |
20140030548 | TURBINE COMPONENT AND A PROCESS OF FABRICATING A TURBINE COMPONENT - A turbine component and a process of fabricating a component are disclosed. The process includes excavating a base metal of the component to form a fill region and filling the fill region with a filler metal. The filler metal has a filler metal elongation that is at least 25% greater than a base metal elongation of the base metal. The filler includes, by weight, between about 4% and about 7% iron, between about 14% and about 17% chromium, between about 15% and about 17% molybdenum, between about 3% and about 5% tungsten, up to about 0.02% carbon, up to about 1% manganese, up to about 2.5% cobalt, and a balance of nickel and/or the filler metal elongation is greater than about 35% in/in per two inches. | 01-30-2014 |
20140059964 | CRACK-RESISTANT MEMBER, A METHOD OF PREVENTING CRACK PROPAGATION, AND A METHOD OF ASSEMBLING A TOWER - A crack-resistant member for preventing crack propagation, a method of preventing crack propagation, and method of assembly a tower are provided. The crack-resistant member includes at least one insert attached to at least one removed portion at a predetermined location along a girth weld and adjacent a heat affected zone of the tower. The at least one insert is positioned perpendicular to a weld direction and intersecting the girth weld. The at least one insert prevents crack propagation in the girth weld of the tower. | 03-06-2014 |
20140099194 | BIMETALLIC TURBINE SHROUD AND METHOD OF FABRICATING - A bimetallic ring for use as a turbine shroud in a gas turbine engine. The bimetallic ring forms a sealing surface as a hot gas flow path boundary in the engine. The ring is comprised of two materials. The first material, a wrought, oxidation resistant metal alloy comprises a first portion, which is the hot gas flow path sealing surface. The second material, a low cost low alloy steel, comprises a second portion that may be at least a pair of supporting side plates. A dissimilar weld joint joins the sealing surface to the second portion, the at least pair of supporting side plates. | 04-10-2014 |
20140208676 | CRACK RESISTANT MEMBER AND TOWER - A crack-resistant member for preventing crack propagation, a method of preventing crack propagation, and method of assembly a tower are provided. The crack-resistant member includes at least one insert attached to at least one removed portion at a predetermined location along a girth weld and adjacent a heat affected zone of the tower. The at least one insert is positioned perpendicular to a weld direction and intersecting the girth weld. The at least one insert prevents crack propagation in the girth weld of the tower. | 07-31-2014 |
20140220376 | BRAZING PROCESS, BRAZE ARRANGEMENT, AND BRAZED ARTICLE - A brazing process, a braze arrangement, and a brazed article are disclosed. The brazing process includes brazing an article with a braze arrangement. The braze arrangement includes a first braze material and a second braze material, the first braze material having a first melting point and the second braze material having a second melting point, the first melting point differing from the second melting point. The brazed article includes a treatment region, a first brazed material positioned within the treatment region, and a second brazed material positioned distal from the article in comparison to the first brazed material. The first brazed material is formed by the first braze material and the second brazed material is formed by the second braze material. | 08-07-2014 |
