Friction stirring interlocking of dissimilar materials
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.
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.
