Abstract
An apparatus is provided for joining electrically conductive materials by friction stir welding. The apparatus includes a shaft portion for being received by a rotation imparting apparatus, and a second end having a cut-away portion configured for deflecting plasticized material during friction stir welding. A pilot formed of a material harder than the electrically conductive material extends from the second end. The pilot is configured and dimensioned for friction stir welding electrically conductive members together.
