“…As was demonstrated in investigations carried out earlier by a number of researchers, the dispersive behavior of UGW is strongly dependent on the bonding state between lap joint connected objects [27,[29][30][31][32]45,46]. Thus, the velocity and amplitude of UGW signals transmitted through lap joint are among the main parameters to be affected [27][28][29].…”

Abstract:The objective of the research presented here is the investigation of ultrasonic guided wave (UGW) propagation through the lap joint welded plates used in the construction of a storage tank floors. The investigations have been performed using numerical simulation by finite element method (FEM) and tested by measurement of the transmission losses of the guided waves transmitted through the welded lap joints. Propagation of the symmetric S 0 mode in the welded stainless steel plates in the cases of different lap joint overlap width, operation frequency, and additional plate bonding caused by corrosion were investigated. It was shown that the transmission losses of the S 0 mode can vary in the range of 2 dB to 8 dB depending on the ratio between lap joint width and wavelength. It was also demonstrated that additional bonding in the overlap zone caused by corrosion can essentially reduce transmission losses.

“…A huge amount of work has been produced on the general topic of UGW propagation in lap joint connected objects, mainly targeting adhesively bonded [27][28][29][30][31][32], bolted [33], and brazed [34] lap joints. However, little attention was paid to metal plates joined using lap welds.…”

“…e result showed phase velocity changed slightly when the state of the adhesive layer changed from properly bond to poorly bond. Siryabe et al [22] excited the Lamb wave by an air-coupled transducer in the aluminum substrate and analyzed the time-frequency relationship of S 0 under different bonding conditions. Castaings [23] found that SH0 was sensitive to the change of properties of the interfacial adhesive, which can analyze the bonding quality by quantifying the shear properties at the interface.…”

The aim of the investigation presented here was to understand how the viscosity parameters of an adhesive layer affect group velocity and attenuation of the double-layer adhered pipe. Various parameter combinations (attenuation of longitudinal wave and shear wave, pαL and qαT; thickness, d; and density, nρ) were utilized in order to generate different uncured degrees of the adhesive layer. In the frequency range 0∼500 kHz, the group velocity dispersion curves and attenuation dispersion curves were obtained from these models. Then, the group velocity and attenuation of the two commonly used modes, L0,2 and T0,1, were compared and analyzed. The results have shown that it is important to remark that little effect on group velocity was caused, and significant linear increases of attenuation occur with increase in q, d, and n. However, variable p had little effect on attenuation; more modes emerged when d increased or n decreased, causing difficulties on mode identification and signal processing. The numerical results provided a useful way to evaluate bonding quality by measuring the group velocity and attenuation in the pipelines.

“…NDT of the bond integrity of multi-layered structures is of interest and of practical value, which is why a large body of research literature has been published on the subject. Traditional ultrasound longitudinal and shear bulk waves [7][8][9], as well as more recently Lamb or Shear-Horizontal (SH) guided waves [10][11][12] are ultrasound techniques that get increasingly applied to inspect the bond of multi-layered bonds. Shearography [13][14][15] and Thermography [15][16][17][18] are innovative optical techniques that allow full-field, non-contact and speedy detection in composite materials.…”

A feasibility study on different NDT techniques used for testing bond quality in cold roll bonded Al-Sn alloy/steel bimetal strips

-This paper presents non-destructive testing (NDT) results for the detection of bond defects in aluminiumtin (Al-Sn) alloy/steel bimetal strips. Among all types of bimetal strip that are used in the automotive industry for plain journal engine bearings, Al-Sn alloys cold roll bonded (CRB) onto steel backing is the most common type. The difficulty to evaluate the metallurgical bond between the two dissimilar metals is a major industrial concern, which comprises the risk that bearings fail in the field. Considering the harsh performance requirements, 100% online non-destructive testing would be desirable to significantly reduce the business risk. Nowadays bimetal strip manufacturers still rely on destructive testing through different peel-off tests. This work offers the results from four independent NDT studies, using active thermography, shearography, ultrasound and guided wave electromagnetic acoustic transducers (EMATs) and samples with different artificially implanted defects, to explore the feasibility to qualitatively indicate the occurrence of bond defects. A destructive peel off test was used to correlate the NDT results with known bond quality. The studies were done under laboratory conditions, and in case of ultrasound also online under production conditions. During the ultrasound online test, the requirements that a NDT technique has to fulfil for online inspection of Al-Sn alloy/steel bimetal strip were established. For active thermography, shearography and guided wave EMAT techniques, it was theoretically analysed, if the laboratory test results could be transferred to testing under production conditions. As a result, guided waves using EMATs, among the four tested methods, are best suited for online inspection of Al-Sn alloy/steel bimetal strip. This research was carried out in collaboration with MAHLE Engine Systems UK Ltd., an Al-Sn alloy/steel bimetal strip manufacturer for the automotive industry.
