Problems solved by technology

this process is time consuming
Also, even with this measure, when the parts are arranged and pressed together to form the joint, some sealant may squeeze into the interface and mix with the plasticized material of the joint, degrading the quality of the welded joint
Also, as mentioned above, voids may form in the interface during the joining process, or the sealant may subsequently loosen from the interface

Embodiment Construction

[0018] The present invention will now be described in more detail with reference to the accompanying drawings, in which some, but not all, embodiments are shown. Indeed, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will satisfy appropriate legal requirements. In the drawings, the same reference numerals denote the same elements.

[0019] Referring now to the drawings, and in particular to FIG. 1, there is shown an apparatus for forming a joint 10 for connecting first and second structural members 20, 22. The method of the present invention typically joins two structural components, but it can also join a single structural component, such as a pipe component or other curved component with adjoining edges. Three or more structural members may also be optionally connected, and the structural members may be arranged in various configurations. A...

Abstract

A joint between one or more structural members and an associated method are provided. The joint includes a friction stir welded joint or other connection between faying surfaces of the members, and an exothermically reacted sealant disposed in an interface defined by the faying surfaces. The exothermic reaction of the sealant in the interface can be initiated before, during, or after joining the structural members such that the sealant at least partially seals the interface. The sealant can fill the spaces between the structural members to prevent the entry of chemicals, moisture, debris, and other substances, thereby reducing the likelihood of corrosion of the joint or structural members at the interface. Further, the sealant can form a bond with the structural members, thereby increasing the strength of the connection between the members.

Description

technical field [0001] The present invention relates to the connection of structural components, and in particular to the sealing of joints between structural components, for example to increase the strength and corrosion resistance of the components. Background technique [0002] The connection of structural components often results in the formation of an interface into which chemicals, moisture or other fluids and particles are prone to intrusion. For example, in the aircraft industry, joints between structural components are often formed by overlapping two or more structural components, forming holes through the components, and placing rivets or other fasteners through the holes. Although overlapping components may closely correspond to each other at their interfaces, each interface typically defines a narrow space or crack-like gap through which moisture, chemicals, debris, or other foreign materials can enter , and may lead to increased corrosion of structural componen...
