Abstract
Official abstract text for this publication.
A method of making a fluid injection component for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining an elbow into the deposited material, wherein machining the elbow includes forming a braze joint surface in the deposited material. Depositing can include laser cladding the material onto the piece of tube stock.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a fluid injection component for a gas turbine engine comprising: depositing material onto a piece of tube stock; and machining an elbow into the deposited material, wherein machining the elbow includes forming a joint surface in the deposited material, wherein depositing material includes depositing material to cover over an end of the piece of tube stock so fluid cannot flow out the end of the piece of tube stock. 2. The method as recited in claim 1 , wherein depositing includes laser cladding the material onto the piece of tube stock. 3. The method as recited in claim 1 , wherein the piece of tube stock is a feed arm of a fluid injector. 4. The method as recited in claim 1 , wherein depositing material includes depositing material around a whole circumference of an outer surface of the piece of tube stock. 5. The method as recited in claim 1 , wherein forming the joint surface includes machining a braze joint surface to be lateral to the piece of tube stock. 6. The method as recited in claim 1 , further comprising joining a fluid nozzle to the joint surface of the deposited material. 7. The method as recited in claim 1 , wherein machining includes forming a fluid passage through the deposited material and through a lateral wall of the piece of tube stock in fluid communication with a main fluid passage in the piece of tube stock. 8. The method as recited in claim 7 , further comprising brazing a fluid nozzle to a braze joint surface of the deposited material, wherein the fluid passage extends from the piece of tube stock, through the elbow, and into a nozzle component. 9. The method as recited in claim 1 , further comprising forming a bend in the piece of tube stock. 10. The method as recited in claim 1 , wherein machining includes forming a second braze joint surface in the deposited material and further comprising brazing a heat shield to the second braze joint surface. 11. The method as recited in claim 1 , wherein depositing material includes depositing the material to form a fillet interface with the piece of tube stock.
