Bolted connections are prone to loosening, deformation, defects, and even fractures in the oil well environment, which can cause adverse consequences to the wellhead blowout preventer. Ultrasonic testing is a nondestructive testing method widely used in metal material testing. This experiment uses M10 bolts as test samples, then will use wire cutting equipment to simulate the damage of bolts in a cutting form, simulate the prefabricated cracks of bolts, and then use piezoelectric chips pasted on the bolt head to collect ultrasonic signals. Three different devices, including ordinary ultrasonic emission and reception equipment, nonlinear ultrasonic, and UA-360 ultrasonic wave detection equipment, will be used, and different load forces will be applied to the bolts using an electronic universal tensile testing machine, By collecting ultrasonic signals before and after prefabricated bolt cracks, as well as under different axial stresses, the relationship between external load and prefabricated bolt cracks on accelerating bolt failure can be identified. And at the same time, the macroscopic morphology and microstructure of the bolt fracture were analyzed. Through the analysis of the bolt cross-section image, it can be concluded that the failure of the bolt is all affected by the prefabricated cracks.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1236 - 1248"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study provided an in-depth analysis of the fatigue behavior of V-groove butt weld joints in small-bore steel piping systems under vibration conditions, focusing on the influence of various weld filler metals and base materials. An advanced experimental setup simulated dynamic vibrations to examine the effects of different welding wire compositions on fatigue strength, damage susceptibility, and fracture tendencies. Finite Element Analysis (FEA) was employed to investigate stress distributions, revealing significant stress concentrations and deviations from the acceptable fatigue limits defined by industry standards. The study utilized nondestructive testing methods, including magnetic particle inspection (MPI) and radiographic testing (RT) were used to identify and monitor weld discontinuities, emphasizing the importance of continuous inspection with these methods to ensure weld integrity under dynamic loading conditions. Microstructural analysis revealed that manganese-enriched welds promote acicular ferrite formation, enhancing hardness, while high nickel content increases discontinuities and lowers toughness. Optimal manganese levels (0.6–1.4 wt %) improve mechanical properties, but excessive manganese combined with nickel adversely affects fatigue performance. The study emphasized the need for optimized alloy composition and design to enhance fatigue resistance in small-bore pipe welds, offering insights for improving long-term reliability. This research deepened the understanding of vibration-induced fatigue and informed better design and maintenance protocols for steel piping systems.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1293 - 1304"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained values of tension forces and bending stiffness were in the expected range. The high variability in the values of bending stiffness prompted attention to the accuracy of the initial cable length values, which were obtained from a photograph. To refine the cable length, a method of recording nodal harmonics was proposed, but the results obtained by this method turned out to be higher than those obtained from the photograph. The error analysis of the measurements could not explain this overestimation, leading to the need to reconsider the solution of the differential equation for transverse vibrations. It was found that only its particular solution, assuming a hinged support for the cable, had been considered earlier, while in reality, it is cantilevered and has a bending response. Accounting for this feature by introducing an additional boundary condition allowed the improvement of the calculation model and explained the overestimation of the cable length in the nodal harmonics method. Taking into account the type of cable attachment allowed the introduction of a generalized parameter (s) that takes a value of zero for a rigid cantilever attachment and a value of one for a hinged attachment. In this case, a reduction in stiffness within the attachment manifests itself as an increase in the parameter (s), which can be detected through the vibration spectrum recording results.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1280 - 1292"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To detect these defects, ultrasonic detection is widely used by railway maintenance practice. However, the presence of coarse grains and inclusions in the welding joint leads to numerous backscattering noise in the ultrasonic signal, interfering with defect detection. To address this issue, this paper proposes an adaptive ultrasonic signal reconstruction method VSKR (VMD-SVD-Kurtosis Reconstruction) and introduces a new metric named rail peak signal noise ratio (RPSNR) to measure the effectiveness of this method. This method capitalizes on the distinct frequency characteristics between the noise signals and defect signals, and utilizes variational mode decomposition (VMD) algorithm. VSKR has been successfully applied to signals obtained from both finite element models and real experiments, defect echoes in those signals are highlighted, demonstrating the effectiveness of VSKR. In a specific condition, the RPSNR value has been increased by 8.94 dB. The average increased value of RPSNR is 4.90 dB. These indicates that VSKR can enhance the efficiency of ultrasonic detection of rail welding joint defect by broadening the range of probe positions and directions capable of detecting defects.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1249 - 1262"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this difficulty, the acquisition frequency and the number of bits are taken as the research object to realize the optimization of the echo signal. By combining FEM simulations with Comsol software with experimental research, the effects of probe incidence angle, probe spacing, and temperature on ultrasonic waves are investigated, and the relationship between probe spacing and the stress coefficient of measured component (K) is analyzed. A novel ultrasonic synchronous detection method for residual stress and thickness is proposed. This method is based on an integrated transmit-receive probe with oblique incidence, utilizing critical refracted longitudinal wave (LCR wave) for stress detection and synchronously generated transverse waves for thickness measurement. For the first time, a formula for ultrasonic thickness measurement based on inclined incidence is derived. Using self-developed equipment, ultrasonic testing experiments on step test block and cantilever beam loading device were conducted to verify the accuracy and precision of the proposed synchronous detection method for stress and thickness. This method has significant application prospects in the inspection or online monitoring of pressure vessels concerned with fatigue and corrosion performance.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1221 - 1235"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To compete with the conventional fabrication route, additive manufacturing (AM) technology must progress with appropriate NDE methods to ensure defect-free components. The common defects noticed in the AM components are gas porosities, clusters of porosities, micro-cracks, balling, lack of fusion and layer delamination among others. This paper aims to inspect subsurface defects in AM products which are one of the more challenging issues in AM. The surface finish of the AM components in as-printed condition is not amenable for the detection of subsurface defects for NDE using contact methods, e.g. ultrasonic techniques. Laser shearography and pulsed thermography by thermal excitation are extensively used as noncontact NDT techniques for the detection of subsurface defects in composite materials. Noncontacting NDT techniques may play a significant role in the in-process inspection of AM components, especially subsurface defects. This paper presents the capability, advantages and limitations of pulsed thermography and laser shearography techniques for the assessment of engineered defects in aluminum alloy coupon made through the laser powder bed fusion (LPBF) AM process.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1314 - 1324"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach begins by employing a deep neural network to extract weak weld features from X-ray images. A channel attention module is introduced to balance the importance of different feature weights, enhancing the network’s ability to focus on key features. An atrous spatial pyramid pooling module is then utilized to expand the receptive field, effectively leveraging the spatial hierarchical information within the X-ray images. Additionally, a multi-scale feature fusion module is applied to automatically learn feature relationships, capturing semantic information at various scales, which significantly improves the distinction between defective and normal weld regions. The method’s effectiveness is validated through repeated experiments on the GDXray weld dataset and a self-constructed UHV weld dataset. Quantitative comparisons demonstrate that the proposed method significantly enhances the segmentation accuracy of weld defects in UHV equipment, providing a valuable tool for technicians in the field of weld non-destructive testing.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 11","pages":"1305 - 1313"},"PeriodicalIF":0.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
