ABSTRACT:
A method of obtaining effective faying in joining parts includes forming a first and second member into predetermined complementing shapes. The members are then placed together and sealed along a peripheral track to form a chamber between the members. The method further includes applying a pressure differential to the members with the lesser pressure residing in the chamber and heating the members to soften at least one of the members to conform the members to each other under the force of the differential pressure.
