Noise Analysis During Ultrasonic Testing of Titanium Alloys

Aiming at analyzing the mechanism of high noisy level during ultrasonic testing of titanium plates and bars, three aspects of microstructure, surface roughness of workpiece and probe frequency were tested and analyzed. Results showed that in addition to the effect of microstructure on ultrasonic testing noise of the titanium alloys, the roughness of the workpiece and the probe frequency both had great influence on noisy level, as well.
