Abstract
A heat assisted friction stir welding system and fastener for use therewith allows the joining a variety of dissimilar materials, including joining composites and plastics to metal, in which the fastener becomes part of the bond. The fastener can be constructed from multiple materials, allowing for the joining of dissimilar metals. Heating the materials to be joined reduces the clamping force and torque required by the friction stir weld process. The result is a bond that is stronger with less energy input.
