“…Meyghani and Awang [104] performed a thermomechanical simulation and compared the FSW for fat and curved geometries (Figure 7 temperature and stress behavior were approximately asymmetric on diferent sides of the tool. In the tool front and back sides for both the fat and the curved models an approximately diferent behavior was observed, while, there were some similarities in the temperature behavior at the advancing and the retreating sides.…”

The permanent metal joining processes play a vital role in assembling the complex aluminium structures of the aerospace, automotive, marine, and oil industries. The invention of friction stir welding (FSW) redefined the mechanism of metal joining to produce high-quality welds by eliminating the consumption of electrodes and shielding gases, resulting in economical processes. Research works still lack to explore the application of FSW in complex geometries. In this view, the present work reports a critical review of various geometries welded by FSW, mainly circular geometries that are majorly used in the oil and gas industries. The various aspects of the FSW of pipes, such as process facilitation, process parameters, tool material selection, and tool design selection are discussed. The paper also presents insights into the parameters responsible for the weld quality, the feasibility of optimization techniques, and the status of various fixture arrangements. The facilitation requisites for FSW of pipes are also provided based on the reviews made. The review concludes by discussing the challenges associated with the FSW of pipes, economic aspects, and future research directions.

“…In general, ALE has the Lagrangian part for solving large displacements and the Eulerian part for solving the advection issues of velocities. Thus, the major objective of this method can be the local level simulation (inside the HAZ area) [102]. At the local level simulation, the impact of the speed of welding (transverse and rotational), the mechanisms of contact, the shape of the pin, the size of the stir zone, and the material flow inside the stirring zone can be studied with very high accuracy [103,104].…”

This article reviews the status of thermomechanical analysis of the friction stir welding (FSW) process for establishing guidelines for further investigation, filling the available research gaps, and expanding FSW applications. Firstly, the advantages and applications of FSW process are introduced, and the significance and key issues for thermomechanical analysis in FSW are pointed out. Then, solid mechanic and fluid dynamic methods in modeling FSW process are described, and the key issues in modeling FSW are discussed. Different available mesh modeling techniques including the applications, benefits and shortcomings are explained. After that, at different subsections, the thermomechanical analysis in FSW of aluminum alloys and steels are examined and summarized in depth. Finally, the conclusions and summary are presented in order to investigate the lack of knowledge and the possibilities for future study of each method and each material.

“…It has been observed that fatigue life and ultimate tensile strength (UTS) of the FSW joint have been decreased drastically in comparison to the base metal. Meyghani and Awang (2020) experimentally investigated and compared the thermo-mechanically behaviour of the FSW process with a flat and curved welding path. Results reported that stress and temperature for curved welding paths are lower than the flat path because of less penetration of tool pin in the workpiece.…”

Purpose This paper aims to predict the performance of friction stir welded AA8090 joint. Design/methodology/approach In the present study, Al-Li AA8090 plates are butt joined using friction stir welding (FSW). The experiments are designed and optimized using a Taguchi-orthogonal array. The experiments are conducted at three different process parameters, i.e. tool rotational speed (TRS), tool transverse speed (TTS) and dwell time (DT). The ultimate tensile strength (UTS) and microhardness (MH) are considered as response parameters. In addition, a statistical tool (ANOVA) is used to check the adequacy of experiment results. Findings The maximum UTS of 220 MPa is obtained at a TRS of 1,400 rpm, tool TTS of 40 mm/min and DT of 15 s. The maximum microhardness is obtained for 1,400 rpm, 25 mm/min and 8 s, i.e. 108.6 HV. The microstructural showed that the minimum grain is observed at the nugget zone. Fractography analysis revealed the ductile behaviour of fractured surfaces. Originality/value From the reported literature, it has been observed that very limited work is reported on the FSW of AA8090 alloy. Further, the thermal behaviour of welded joint is also observed in this experimental work.
