    Phased Array Ultrasonic (PAUT) System for Weld inspection and Corrosion Mapping at Elevated Temperatures (Up to 350°C) at Elevated Temperatures (Up to 350°C)

    Acuren’s Research and Application Development group, in partnership with Eclipse Scientific developed a phased array inspection system for use at elevated temperatures. The system includes wedges build from plastics resistant to high temperature degradation and equipped with a cooling jacket around the array. The effects of temperature on the ultrasonic beamset generated in the piece has been exhaustively studied and compensated for using a model of the ultrasonic beam skew pattern due to thermal gradient inside a wedge. The output of this model allows the focal laws for any standard beamset to be corrected for the effects of temperature via the BeamTool high temperature module. Performance of the phased array inspection system has been fully validated including the effects of focal law correction on defect proper positioning of defects detected at elevated temperatures. This system is widely used in industrial sites for inspection of engineering components at elevated temperatures.
