Sažetak
In conventional ultrasonic nondestructive condition monitoring, the testing personnel use their testing experience to interpret defects by analyzing the ultrasonic echo. Owing to the coarse material structure, the ultrasonic waves are more attenuated and from time to time they give a deceitful impression of defect and thus provide unreliable results. The conventional inspection method is too subjective to be used and highly relies on the effectiveness of testing personnel and consequently inspection reliability is very low. Therefore, to mitigate these limitations, a multi-interrogation ultrasonic technique and correlation of several parameters such as attenuation, acoustic velocity and grain size with material features are covered by this paper.
