Patent 7561281 was granted and assigned to Lockheed Martin on July, 2009 by the United States Patent and Trademark Office.
The invention is directed to a system and method for implementing process control for tubing thickness using sonic NDE techniques. The system may, for example, generate ultrasound waves in a test object during the manufacturing process. A detector such as an interferometer may be used to detect the ultrasound waves. An interpreter or analyzer may determine the tubing or sheet thickness from the waves. Then, a control system may determine and implement an appropriate control action on the process.
