Abstract: A method of repairing a braze joint (16) and the resulting joint includes removing an unsuitable portion (20) of a first joining material (18) in a joint (16) between a first member (12) and a second member (14) of an aerospace assembly (10) and cleaning the joint (16). A stripping solution is used to remove the unsuitable portion (20) of the first joining material (18). A first cleaning solution is used to clean the joint (16), and the joint (16) is further cleaned using a second cleaning solution. During a rebrazing step, a second joining material (60) moves into a void left by the removed unsuitable portion (20) from the removal step to form a new joint between the first member (12) and the second member (14) that includes the remaining first joining material (18) and the second joining material (60).
