RESEARCH WITH ULTRASONIC INVESTIGATION ON ALUMINUM BARS USING THE PULSE-ECHO METHOD

This paper presents a study case on ultrasonic investigation of an aluminum bar having artificially defects. In particular, using this method reflects the detection of defects in the shadows and the defects located in the near field of the transducer with the examined part. The purpose of this research is to get good results in solving various problems that arise frequently in the production system. The methodology used to verify parts with ultrasonic investigation has the ability to inspect in a nondestructive way, to evaluate and characterize the integrity of the parts. The final conclusions from the experimental results follow up the analysis of factors impact on ultrasonic investigations.
