Abstract
The disclosure describes assemblies, systems, and techniques for reinforcing complex geometries of pressure vessels using a pre-sintered preform (PSP) braze material that includes a low-melt powder and a high-melt powder. An example component includes a substrate comprising at least a portion of a pressure vessel. The substrate defines a contoured exterior surface of the pressure vessel. The component includes a pre-sintered preform (PSP) reinforcement formed on the surface of the substrate by brazing, wherein the PSP reinforcement comprises a low-melt powder and a high-melt powder.
