Abstract: A system is for bonding a cover sheet to a core to form or repair a dual wall structure. The system includes a cover sheet probe and an inner pedestal probe. A three dimensional contoured tip of the cover sheet probe abuts against a three dimensional contoured outer surface of the cover sheet opposite a pedestal of the core. The pedestal abuts the inner surface of the cover sheet. The inner pedestal probe may be coupled to the core to create a conductive electrical path from the cover sheet probe through at least part of the structure. A flow of electric power is controlled and supplied to the cover sheet probe to heat a junction between the area of the cover sheet abutting the pedestal and the pedestal. A heated area is created in the junction and fixedly couples the coversheet and the pedestal.

Abstract: A method of diffusion bonding utilizing vapor deposition comprises depositing a coating from a vapor comprising a temperature suppressant element onto a surface of a first component comprising a metal alloy, thereby forming a vapor deposited coating comprising the temperature suppressant element; assembling the first component with a second component comprising a mating surface to form an assembly, the vapor deposited coating contacting the mating surface; and exposing the assembly to a bonding temperature and a compressive force, thereby diffusion bonding the first component to the second component and forming a monolithic third component.
