Abstract
Official abstract text for this publication.
A system and method for joining dissimilar metals. In one embodiment, a method comprises providing a first metal plate, a second metal plate, and an intermediate body that is positioned between the first metal plate and the second metal plate. The first metal plate is then driven into the intermediate body, which causes at least a portion of the intermediate body to collide with the second metal plate. As a result, the material of the intermediate body joins the first metal plate to the second plate. In another embodiment, a method for joining dissimilar metals comprises providing a first metal that is not amenable to welding, a second metal that is joinable to the first metal, and an intermediate body that is not joinable to at least the first metal. The intermediate body may have at least one hole such that the first metal and the second metal are positioned over and on opposite sides of the hole(s). At least a portion of the second metal may then be driven into the hole(s) to be joined to first metal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for joining dissimilar metals, said method comprising the steps of: providing a first metal, a second metal that is dissimilar to said first metal, and an intermediate body comprised of a carbon fiber composite and having at least one hole such that said first metal and said second metal are positioned on opposite sides of said intermediate body and over said at least one hole; and driving at least a portion of said second metal into said hole such that said second metal is welded to said first metal, and said intermediate body is trapped between said first metal and said second metal. 2. The method of claim 1 further comprising the step of providing a vaporizing foil actuator that drives said portion of said second metal into said hole such that said second metal is joined to said first metal. 3. The method of claim 1 , wherein said intermediate body has a plurality of said holes such that said second metal is welded to said first metal through each of said holes.
