Appl. No.:

12/539595

Inventors:

Jonathan A. Babb - West Jordan UT, US
Russell Steel - Salem UT, US
Scott M. Packer - Alpine UT, US
John Williams - Alpine UT, US

Assignee:

Megastir Technologies LLC - Provo UT

International Classification:

B23K 31/02
B23K 20/12

US Classification:

2281121, 228 21

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.

Appl. No.:

12/583005

Inventors:

Assignee:

Megastir Technologies LLC - Provo UT

International Classification:

B23K 20/12

US Classification:

266274, 2281121

Abstract:

A tool is provided that is capable of friction stir processing, friction stir mixing, and friction stir welding of high melting temperature and low melting temperature materials, wherein the collar is now divided into at least an inner and an outer collar coupled to the shank and the FSW tip, wherein new thermal barriers enable expansion of the inner collar to be directed inward to thereby create compression on the FSW tip instead of allowing the FSW tip to become loose in the tool at elevated temperatures.

Appl. No.:

13/196726

Inventors:

Russell Kingston - West Jordan UT, US
Murray Mahoney - Midway UT, US
Russell J Steel - Salem UT, US
Scott M. Packer - Alpine UT, US

Assignee:

Megastir Technologies LLC - Provo UT

International Classification:

B23K 20/12
B23K 31/02

US Classification:

2281121, 228159

Abstract:

A method is taught for creating a hollow sphere that is created by joining two cylinders together that have a semispherical hollow formed in the ends being joined together, wherein a metallic reinforcing disk is inserted at an interface between the two ends of the cylinders, wherein the two cylinders and reinforcing disk are joined using friction stir welding to create an inner sphere from the two hemispherical hollows that is bisected by the metallic reinforcing disk, and wherein the joined cylinders and reinforcing disk are machined to thereby create an outer spherical surface that is centered around the inner sphere.

International Classification:

B23K 31/02
B23K 20/12

US Classification:

2281121, 228 21, 228102

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.
