  • Deposition of braze preform
    Patent number: 10252365
    Abstract: A method of manufacturing includes depositing a braze filler adjacent to a void between a first component and a second component thus holding the components in position before brazing. The first and second components are heated to melt and flow the braze filler into the void. A braze joint is formed between the first and second components by cooling the braze filler. Depositing the braze filler can include laser cladding the braze filler to the first and/or second components adjacent the void. The method also optionally includes welding the first and second components in position with the braze filler adjacent to the void. The braze filler may be deposited as a powder, cold spray, melted brazed filament, spherical ball or any other suitable form.
