SYSTEM AND METHOD FOR CONTROLLING TUBE THICKNESS WITH ULTRASOUND

摘要

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 (158) during the manufacturing process. A detector such as an interferometer (162, 174) 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 (164) may determine and implement an appropriate control action on the process (166).
