Ultrasonic Gauging Technology for High Pressure Tubine Blade

Due to the characteristics of high-pressure turbine blade, such as the complex cavity channels and large torsion angle, appropriate ultrasonic c thickness gauge, probe, standard part and positioning template are therefore selected. Through ultrasonic thickness measurement experiments on measuring point of blade, procedures of high-pressure turbine blade ultrasonic thickness measurement is determined. As compared with the real thickness, the ultrasonic thickness results are proved accurate and reliable.
