| 20110095000 | WORKPIECE AND WELDING PROCESS FOR PREVENTING POROSITY IN A FORMED WELD - An article and method of forming the article are disclosed. The method includes positioning a first workpiece, positioning a second workpiece, and applying energy to the first workpiece and the second workpiece to form a weld. The article includes the first and second workpiece. The first workpiece includes a first weld surface, which includes at least one porosity reducing channel. The second workpiece includes a second weld surface positioned to be welded to the first weld surface. The application of energy generates gas that is directed by the at least one porosity reducing channel. | 04-28-2011 |
| 20090142195 | Shank shape for a turbine blade and turbine incorporating the same - A turbine includes a turbine wheel having a plurality of buckets, each of the buckets including a bucket airfoil, a bucket dovetail to connect the bucket to a turbine wheel and a shank shape to connect the airfoil to the bucket dovetail, the shank having an uncoated nominal profile including a concave, pressure side, substantially in accordance with Cartesian values of X, Y and Z′ set forth in Table I wherein the Z′ values are non-dimensional values in a range from 0 to 1 convertible to Z distances in inches by multiplying the Z′ values by shank height in inches, and a convex, suction side, substantially in accordance with Cartesian values of X, Y and Z′ set forth in Table II wherein the Z′ values are non-dimensional values in a range from 0 to 1 convertible to Z distances in inches by multiplying the Z′ values by the shank height in inches. The X and Y are distances in inches which, when connected by smooth continuing arcs, define a shank profile section at each distance Z, the profile sections being joined smoothly with one another to form a complete shank shape. | 06-04-2009 |
| 20090136347 | Turbine bucket shroud internal core profile - A turbine bucket including a bucket airfoil having a hollow tip shroud, the hollow tip shroud having a hollow core having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I, in inches, wherein the shape of the core is defined by the cloud of points listed which are distributed around each surface of the shroud, and the complete hollow portion of the tip shroud could be constructed by defining smooth sheet surfaces through the listed points. | 05-28-2009 |
