摘要： 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.

摘要： A fatigue load resistant structure includes a fatigue loaded portion and a weldable fatigue loading resistant feature. The fatigue loaded portion includes a first elongation material. The weldable fatigue loading resistant feature includes a second elongation material secured to the fatigue loaded portion of the fatigue loaded structure. The first elongation material is less ductile than the second elongation material, and the weldable fatigue loading resistant feature can reduce, retard, or eliminate formation of cracks due to tensile and compressive forces.

摘要： 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.

摘要： 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.
