Research Institution
Current manufacturing processes can not meet the worldwide demand for wind turbines. One of the bottlenecks involves the stringent inspection requirements for the welds used for wind turbine tower assembly. Current inspection techniques, which are labor intensive, are applied after the process is complete. This project will develop a laser ultrasonic technique for the inspection of the welds used in tower assembly. The technique will be a completely noncontact process, ideally suited for automated in-line inspection. Commercial Applications and other Benefits as described by the awardee: The proposed inspection technique should enable the manufacturing of wind turbines at lower cost and increase the number of towers available each year. Related techniques also could be used for the inspection of turbine blades
