Patents by Inventor Tommy BRUNZEL

Tommy BRUNZEL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Friction Stir Processing Tool Having Non-Circumferential Shoulder and Friction Stir Processing Method Performable Therewith
    Publication number: 20170312989
    Abstract: A friction stir processing tool for friction stir processing includes a shoulder for pressing against a workpiece surface and a pin, which protrudes beyond the shoulder and can be driven to rotate, for plasticizing introduction into at least one workpiece to be processed. The shoulder has an interruption opening on a circumferential region, so that the shoulder is not led around the entire circumference of the pin.

  • Friction Stir Tool, Method for Manufacturing the Same, and Friction Stir Method
    Publication number: 20160199933
    Abstract: A load-optimized friction-stir tool, particularly a two-shoulder friction-stir welding tool, includes a first tool body and a pin formation projecting from the first tool body with a smaller outer diameter compared to the outer diameter of the first tool body. The first tool body and the pin formation are integrally formed and the pin formation has a material distribution in cross section that is different from a uniform distribution over a circular shape. A method for manufacturing the friction-stir tool and a friction-stir method that can be executed with the friction-stir tool are also disclosed.
