A method for joining a first component to a second component with a brazing material, the first component including an aperture for receiving the second component. The method includes positioning the second component within the first component via the aperture to form a gap between an inner surface of the first component and an outer surface of the second component, introducing by capillary action brazing material into the gap between the first component and the second component, and forming a join between the first and second component upon cooling of the brazing material introduced by capillary action. According to this first aspect of the present invention, the capillary flow of brazing material in the gap is diverted via a capillary flow diverter located in the gap between the first and second component.
