Abstract
Official abstract text for this publication.
A method for solid state joining of dissimilar materials using a friction stir welding device wherein a pin is inserted through an aperture defined in a first material and a second material to hold the materials together and then held in place by friction stir welding a portion of the pin to a material adjacent said pin, or by friction stir welding a cap or plug that holds the pin in place to the adjacent material. The result is a connection or join wherein the central portion of the pin is not friction stir welded but the portions holding the pin in place (the ends or caps) generally are.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for solid state joining of dissimilar materials using a friction stir welding device, the method comprising the steps of: inserting a pin having two ends within an aperture defined in a first material and a carbon reinforced composite material; and friction stir welding each end of the pin to a portion of the first material. 2. The method of claim 1 wherein said first material is aluminum. 3. The method of claim 1 wherein said first material is steel. 4. The method of claim 1 wherein said first material is configured in to a C-shape, and the carbon reinforced composite material is embodied in an insert configured to fit within said C-shaped material. 5. A method for solid state joining of dissimilar materials using a friction stir welding device comprising the steps of: inserting an insert within an aperture defined in a first material made of aluminum configured into a C-shape and a second material embodied in an insert configured to fit within said C-shape, and friction stir welding a portion of said insert to a material adjacent to said insert. 6. The method of claim 5 wherein said second material is steel. 7. The method claim 5 wherein said second material is a carbon reinforced composite. 8. The method of claim 5 wherein said insert is a pin has two ends and is friction stir welded in each end to the first material. 9. The method of claim 5 wherein said first material is aluminum and said second material is steel. 10. The method of claim 5 wherein said first material is steel and said second material is aluminum.
