Abstract
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.
Claims10
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.
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.
