vanced ceramic-matrix composites for elevated temperature and wear applications in the aerospace, oil and gas, and electronics industries,” Adonyi told the Welding Journal. “Ongoing discussions with potential R&D partners revolve around the extreme reproducibility and reliability of this closedloop controlled noncontact heating method.” The closed-loop controller uses a movable backwall sliding along the waveguide and magnetron power modulation to control the sample temperature. The system can be used to adjust microwave power to a range of target types, sizes, morphologies, and orientations.

AREVA NP Deploys Ultrasonic Testing Technique During a recent U.S. outage, AREVA NP, Charlotte, N.C., demonstrated new ultrasonic testing techniques. This consisted of off-axis inspection for cracks in a boiling water reactor’s core shroud welds. The approach pairs a phased-array technique and a multiaxis manipulator. According to Craig Ranson, senior vice president of installed base services at AREVA, Inc., this will save customers examination time and personnel radiation exposure. “We are the first supplier to implement a fully demonstrated and documented method for off-axis flaw detection and characterization,” he said. The company developed the tool to generate ultrasonic 16 WELDING JOURNAL / DECEMBER 2016 For info, go to aws.org/adindex For info, go to aws.org/adindex
