  • 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.

  • Patent number: 8469256
    Abstract: A control parameter ramp profile that enables control parameters to be modified in a non-linear manner, such that as a temperature set point of a tool or a weld is approached, the control parameter ramp profile enables the temperature set point to be approached in a manner that prevents temperature overshoot and therefore creating a better weld along the length thereof, wherein the control parameter ramp profile includes but is not limited to proportional, exponential or an S-curve waveform.

  • Patent number: 8157154
    Abstract: A friction stir tool is provided to perform friction stir riveting using a partially consumable pin, wherein the pin includes a cutting edge on a bottom surface thereof, wherein the tool is rotated at a first speed to enable cutting by the pin into a first material that is overlapping a second material, wherein after the pin has cut to a sufficient depth, the rotational speed of the tool is increased to thereby enable plasticization of the consumable pin, the first material, and the second material, wherein the tool is then rapidly decelerated until stopped, enabling diffusion bonding between the pin, the first material and the second material.

  • Publication number: 20110172802
    Abstract: A new control variable is introduced, that when combined with previous dependent control criteria on other variables results in a control program that can create a superior weld while minimizing wear on the FSW tool, wherein the tool repeatedly experiences the same thermal and mechanical loading within specified control windows during every repeated weld sequence because flow stresses and tool loads are driven by temperature, and dependent control loops account for differences in material and heat that is transferred at different rates in varying locations throughout a friction stir weld.
