Abstract: An airfoil for a gas turbine engine according to an example of the present disclosure includes, among other things, an airfoil body defining a recessed region and including at least one rib dimensioned to loop about a respective pocket within a perimeter of the recessed region. At least one cover skin is welded to the airfoil body along the at least one rib to enclose the recessed region. The at least one cover skin is welded to the at least one rib along a respective weld path. The weld path defines a weld width, the at least one rib defines a rib width, and a ratio of the weld width to the rib width is equal to or greater than 3:1 for each position along the weld path. A method of forming a gas turbine engine component is also disclosed.

Abstract: A method for forming a hollow component includes injecting a fluid into an internal cavity of the hollow component to achieve a pressure of the fluid within the internal cavity that is greater than an ambient pressure. The method further includes drilling at least one hole through the hollow component from an external surface of the hollow component to the internal cavity by applying a laser beam to the hollow component with a laser generator. The method further includes directing the fluid from the internal cavity and through the at least one hole so as to exit the hollow component via the at least one hole.

Abstract: A method for treating a substrate prior to metallic coating includes the steps of providing a substrate having a surface to be coated and at least one contaminant selected from as-delivered organics and post-burn out oxides on the surface; treating the surface with a laser to remove the at least one contaminant to produce a cleaned surface on the substrate; and applying a metallic coating to the cleaned surface. Grit blasting can be avoided, and reverse arc transfer cleaning is avoided or minimized, resulting in time savings and less stress on the substrate.

Abstract: A method of removing scale from a casting may include positioning the casting relative to a laser emitter. The casting may comprise a superalloy and the scale may have formed on the surfaces thereof, with the scale being a byproduct of a method of manufacturing the casting. The method may also include passing a laser beam emitted from the laser emitter across the casting such that the laser beam causes the scale to at least one of crack, break, shatter, and spall. The superalloy may be a nickel-based superalloy and the scale may include a metal carbide layer.

Abstract: A method of evaluating and validating additive manufacturing operations includes generating a multidimensional space defined by a plurality of bounds, each of the bounds being defined on a distinct parameter of an additive manufacturing process and each of the parameters being directly related to the occurrence of a horizontal lack of fusion flaw, each of the parameters being a dimension in a multi-dimensional coordinate system, determining a coordinate position of at least one additive manufacturing operation within the multi-dimensional coordinate system, and categorizing the operation as free of horizontal lack of fusion flaws when the coordinate position is within the multi-dimensional space.

Abstract: A method or control strategy in a coating apparatus for use in a coating process can include controlling differential gas pressures among multiple selected localized zones in a coating chamber with respect to each other. The controlled differential gas pressure of the multiple selected localized zones is used to influence how a coating deposits on at least one component. The localized zones can be selected from a first localized zone around the component, a second localized zone adjacent the source of coating material, a third localized zone that diverges from the second localized zone toward the first localized zone, and a fourth localized zone that circumscribes at least the third localized zone.
