“…In addition to this, the result of numerical and experimental comparisons showed that the model developed can be effectively used to determine the residual stress and the distortions of welding process. In the study of Ilman et al [9], a stress relieving treatment technique known to be static thermal tensioning was deployed during the application of MIG welding process. Sodium chloride solution of 3.5% concentration was used in the determination of the fatigue crack test without an inhibitor.…”

In this study, a forensic review of residual stress predictions and its impact on welded joints especially the steel pipes during the Tungsten inert gas welding and metal inert gas welding processes were reviewed. It was established that in the case of MIG welding, the effect of residual stress can be reduced after treatment. In the case of TIG welding process, increase in current will lead to deformation and residual stresses. Estimating the residual stress is a challenging task. It is common to predict residual stress using a notch stress intensity factor, a numerical simulation approach coupled with a thermal-mechanical finite element model. Thus, adequate design in welding parameters will help in the optimization of the process to achieve a safe and reliable welded joint during TIG and MIG welding process.

“…Aluminium alloy series 5xxx is a group of alloys based on aluminium–magnesium (Al-Mg) compositions [ 1 ]. These alloys are known for their high strength-to-weight ratio, excellent corrosion resistance, and good formability [ 2 , 3 , 4 ]. Based on these characteristics and their mechanical properties, these alloys are used widely in the automotive and aerospace industries, transportation, and other applications where lightweight and corrosion-resistant materials are required [ 5 , 6 , 7 , 8 , 9 ].…”

This study presents a comprehensive experimental investigation of the high-cycle fatigue (HCF) behaviour of the ductile aluminium alloy AA 5083-H111. The analysed specimens were fabricated in the rolling direction (RD) and transverse direction (TD). The HCF tests were performed in a load control (load ratio R = 0.1) at different loading levels under the loading frequency of 66 Hz up to the final failure of the specimen. The experimental results have shown that the S–N curves of the analysed Al-alloy consist of two linear curves with different slopes. Furthermore, RD-specimens demonstrated longer fatigue life if compared to TD-specimens. This difference was about 25% at the amplitude stress 65 MPa, where the average fatigue lives 276,551 cycles for RD-specimens, and 206,727 cycles for TD-specimens were obtained. Similar behaviour was also found for the lower amplitude stresses and fatigue lives between 106 and 108 cycles. The difference can be caused by large Al6(Mn,Fe) particles which are elongated in the rolling direction and cause higher stress concentrations in the case of TD-specimens. The micrography of the fractured surfaces has shown that the fracture characteristics were typical for the ductile materials and were similar for both specimen orientations.

“…Due to the action of corrosion, the fatigue strength of the welded steel components significantly decreased even after a short exposure time (approximately 10 days). Scanning electron microscopy (SEM) can be used to analyze the corrosion fatigue failure mechanism of welded metallic materials 14–18 . According to fracture analyses, pitting corrosion occurs on the surface of welded metallic materials during corrosion fatigue, which is one of the reasons leading to the nucleation of fatigue cracks 19,20 .…”

Corrosion fatigue experiments are carried out on butt welds of G20Mn5QT cast steel and Q345D hot rolled steel in simulated seawater. The cyclic stress versus number of cycles to failure (S-N) curve was fitted. The mechanism of crack nucleation at different fracture locations and at different stress levels is analysed. The results show that compared with the S-N curve of laboratory air, for the S-N curve of simulated seawater, the number of fatigue failure cycles is significantly reduced when the maximum cyclic stress is less than 190 MPa. At higher stress levels, stress concentrations caused by internal defects near the surface of the weld zone and the heat-affected zone of G20Mn5QT cast steel cause crack nucleation. At lower stress levels, the main reason for crack nucleation is the stress concentration caused by corrosion pitting. However, there are no obvious internal defects in the heat-affected zone of the Q345D steel, and corrosion pitting is the main cause of crack nucleation. The stress concentrations caused by pitting lead to crack nucleation.
