The wide group of large engineering constructions made from welded metal components and modern composite materials during daily exploitation under non-stationary loads, continuous influence of vibrations and complicated environmental conditions have demand of periodical tests in order to avoid appearance and evolution of the defects. All of them have one common feature – large areas to be tested and the complex geometry. The objective is to improve air-coupled and contact type testing techniques for excitation and reception of appropriate modes of ultrasonic guided waves in large and complex structures. Also, to develop inspection techniques which enable to detect required types of internal defects. The air-coupled and contact ultrasonic techniques for investigation of large and complex geometry objects, such as composites for aerospace applications and petroleum tanks, have been developed. The investigation of propagation effects of ultrasonic guided (Lamb) waves in the plates of the tank floor has indicated relation between reconstructed properties of guided waves and expected presence of corrosion deposits.

“…Numerical simulation and experimental investigations also have shown that the transmission losses of the S 0 mode wave propagation through welded lap joint are additive in the direction perpendicular to the weld seams [4][5][6]. The mentioned effect can by be explained by interference of two signals: the signal transmitted through the weld and the signal reflected from the left end of the bottom plate.…”

Abstract:The novel ultrasonic NDT technique based on application of long range guided waves is proposed for detection of defects in a storage tank floor. The technique needs access only to the outer edge of the tank floor and do not require emptying and cleaning inside of the tank. The technique has been developed on the basis of the Lamb wave transmission tomography. The propagation of the guided waves in the tank floor has been carried out using simulation and experimental verification. The results obtained on the reduced size tank and results of in situ experiments are presented
