ABSTRACT
A new method of ultrasonic detecting on forked blades' root of turbine with double crystal and longitudinal wave convex probe and T shape blades' root with great K value miniprobe. Comparing with traditional practice, the feature is higher sensitivity, clear screen pictures, easy to adjust and so on. Only one probe covers the need of detecting same type of blades' roots of different turbines.
