REPAIR OF BRAZED JUNCTION PART, AND REPAIRED ARTICLE

PROBLEM TO BE SOLVED: To provide a simplified method for repairing an aerospace assembly by eliminating need of completely dismantling a first member and a second member from each other by chemically and mechanically removing brazing material, which requires labor before a re-brazing process. SOLUTION: A method for repairing a brazed junction part and a junction part obtained as a result of that are provided. The method includes elimination of incompatible parts of first junction material in the junction part between a first member and a second member in the aerospace assembly, and cleaning the junction part. Stripping liquid is used for removing the incompatible parts of the first junction material. First cleaning liquid is used for cleaning the junction part, and second cleaning agent is used for further cleaning the junction part. During the re-brazing process, second junction material moves to a cavity left after removal of the incompatible part to form a new junction part including ...
