  • Patent number: 9764375
    Abstract: A system and method of joining at least two workpieces together using a friction rivet and a friction rivet cap that are friction stirred together after a cutting tip or cutting feature on the friction rivet cuts through workpieces and is then bonded to the friction rivet cap, and wherein the friction rivet cap may be excluded if the friction rivet includes a hollow in the cutting tip, the hollow being flared after the friction rivets cuts through the workpieces to thereby create an integral rivet cap in the end of the friction rivet.

  • Patent number: 9242308
    Abstract: A system and method for friction stir welding of small diameter tubing, wherein the small diameter tubing is held in a correct position with a grasp sufficient to perform FSW when the tubing is comprised of high melting temperature materials, wherein the small diameter tubing can be rotated by the positioning and holding system while a FSW tool is held stationary, or vice versa, wherein internal mandrels are also described which can fit inside the smaller dimensions of the small diameter tubing and expand to provide a counter force to prevent deformation of the tubing when forces are applied by the FSW tool, wherein new FSW tool geometries are also described which enable the FSW tool to direct more heat on a tool/workpiece interface to counteract a lack of contact between the FSW shoulder and the workpiece because of tube curvature, and wherein the FSW tool is positioned on a small diameter tube by trailing the joint to provide desirable heating at the joint/workpiece interface and surface finishing.
