Abstract
A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.
Claims4
A method of making a fluid injector for a gas turbine engine comprising:
- depositing material onto a piece of tube stock, the piece of tube stock having a terminal axial end defining an opening of the piece of tube stock;
- and
- machining the deposited material into a fluid injector component, wherein the piece of tube stock is a prefilmer, wherein depositing material includes depositing material on the terminal axial end of the piece of tube stock around a full circumference of the terminal axial end such that the deposited material extends axially outward of the terminal axial end and extends radially inward of an inner diameter of the piece of tube stock, and wherein machining includes forming a prefilming surface on an inside portion of the deposited material.
