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 bounds being directly related to the occurrence of a vertical 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 vertical lack of fusion flaws when the coordinate position is within the multi-dimensional space.

Abstract: A weld clad layer having a substantially equiaxed grain microstructure may be formed by forming a repair area in a substrate, depositing a first layer of laser deposition spots in the repair area, and depositing a second layer of laser deposition spots over the first layer of laser deposition spots. The first layer of laser deposition spots may comprise a first laser deposition spot and a second laser deposition spot adjacent to the first laser deposition spot. The first laser deposition spot may solidify prior to deposition of the second laser deposition spot. The first layer of laser deposition spots may comprise titanium or titanium alloy.

Abstract: A method for forming a metallic structure having multiple layers includes providing a main tool having a main formation surface corresponding to a desired shape of a first layer of material. The method also includes depositing the first layer of material on the main formation surface using a cold-spray deposition technique. The method also includes positioning a secondary tool having a secondary formation surface in a portion of a first volume defined by a first surface of the first layer of material. The method also includes depositing a second layer of material on the secondary formation surface using the cold-spray deposition technique. The method also includes removing the secondary tool such that the first volume is positioned between the first layer of material and the second layer of material.

Abstract: A method for forming a metallic structure having a non-linear aperture includes providing a main tool having a formation surface corresponding to a desired structure shape of the metallic structure. The method also includes attaching a removable tool having a shape corresponding to a desired aperture shape of the non-linear aperture to the main tool. The method also includes depositing a layer of material on the formation surface using a cold-spray technique. The method also includes removing the removable tool from the layer of material such that the layer of material defines the non-linear aperture.
