Brazing components and techniques
A method of joining includes applying braze to a braze reservoir in a first component. A second component is engaged to the first component, wherein a joint location is defined between the first and second components. A wicking structure provides flow communication from the braze reservoir to the joint location. The method also includes joining the first and second components together at the joint location by applying heat to the braze to flow the braze from the reservoir through the wicking structure to the joint location to form a braze joint at the joint location.
1. A method of joining comprising:
applying braze to a braze reservoir in a first component;
engaging a second component to the first component, wherein a joint location is defined between the first and second components, wherein a wicking structure provides flow communication from the braze reservoir to the joint location wherein the wicking structure extends radially through the first component;
heating the braze;
flowing the braze from the reservoir through the wicking structure to the joint location; and
joining the first and second components together.
2. A method as recited in claim 1 , wherein engaging the second component to the first component includes engaging the second component to the first component with the first and second components radially nested, wherein the wicking structure is radially between the braze reservoir and the join location, and wherein the joint location and the braze reservoir are radially spaced apart.
3. A method as recited in claim 1 , wherein the first component includes a radial vane, wherein the wicking structure extends radially through the radial vane, and wherein joining the first and second components includes flowing the braze radially outward to the joint location, wherein the joint location is at an end of the radial vane.
4. A method as recited in claim 1 , further comprising additively manufacturing the wicking structure.
5. A method as recited in claim 1 , wherein the wicking structure is additively manufactured as part of at least one of the first or second components.
