Patent ID: 8066173

Claim:
A method for joining a first component and a second component by brazing, the method comprising: bringing a first unthreaded portion of the first component and a second unthreaded portion of the second component into a juxtaposed position with brazing material therebetween, such that the brazing material is in contact with the first unthreaded portion and the second unthreaded portion, and the first component is located in an aperture of the second component when the first unthreaded portion and the second unthreaded portion are brought into the juxtaposed position; causing relative rotation between the first component and the second component to plastically deform the brazing material by rotational shear action and interlock the first unthreaded portion and the second unthreaded portion, wherein the relative rotation consists of a plurality of complete revolutions of the first component relative to the second component to cause substantially uniform plastic deformation of the brazing material; and heating the brazing material, after the plastic deformation of the brazing material and using a heating apparatus, to form a brazed joint between the first component and the second component.
