| Abstract | ||
| In this paper, experimental results of nondestructive ultrasonic testing using longitudinal surface waves (LSAW) were presented. Analysis of real LSAW signals, generated and received by angle transducers, was performed and causes of lateral interference were investigated, optimal angle transducer constructions were offered. Real angle transducer parameters and levels of LSAW signals, reflected from artificial defects in duralumin sample, were evaluated. It was concluded by experimental investigations that LSAW signal magnitude and collateral interference level ratio reaches 24dB. This gives opportunity to perform sufficiently reliable shell product inner surface nondestructive testing using secondary longitudinal surface waves. | ||
