Abstract:
A method for joining a plurality of workpieces includes providing a rotating drive tool. A fastener is secured to the drive tool. The drive tool is then rotatably driven such that a distal end of the fastener rotates against a surface of the plurality of workpieces. A heated material zone is then generated on the plurality of workpieces as caused by friction from the rotation of the fastener against the surface of the plurality of workpieces. The distal end of the fastener is rotatably and axially driven through the heated material zone. Finally, the drive tool is removed from the fastener, such that when the heated material zone cools, a portion of the heated material zone is fused to the fastener.
