“…Ahmad et al [87] employed the thermo-mechanical analysis based on CEL to analyze the flash formation for FSW of steel. It was interesting to note in the study by Chauhan et al [52] based on CEL to predict the material flow defects influenced by the tilt angle. The comparison between the experimental and the predicted defects at a tilt angle of 0° is shown in Fig.…”

In recent studies, critical research interest exists in the thermo-mechanical analysis of the friction stir welding (FSW) process by numerical simulation. In this review, the thermo-mechanical analysis for FSW is overviewed regarding the computational approaches, the heat generation, the temperature, and the material flow behavior. Current concerns, challenges, and opportunities in current studies are discussed considering the application of the thermo-mechanical analysis. Generally, larger computational scale and better computational efficiency are required to allow better spatial resolution in future analysis. The concepts and approaches demonstrated in the thermo-mechanical analysis for FSW open up quantitative prospects for the design of the FSW process.

“…In the computational examination, spatial determination relies on the mesh size. It can be summarized that in the CSM-based analyses, the region near the tool has more attention and the mesh size near the tool area was found to be in the range of 0.2 to 1.0 mm [17,[36][37][38][39]. For CFD based analyses the values of 0.1 to 0.2 mm were reported [40,41].…”

Friction Stir Welding (FSW) is a new solid-state welding technique which finds application in various industries. It involves the joining of metals without any help of fusion or filler material. The joint between two metals can be formed through the combined action of frictional heating and mechanical deformation which is developed due to a rotating tool. The material that flows around the tool undergoes an extreme level of plastic deformation. Rotation generates enough friction and the friction generates sufficient heat to plastify the material. FSW is handy for welding aluminum alloys. However, interest is growing in utilizing the process in a wider range of applications that also employ non aero engine metallic materials. Therefore, it is the objective of this to provide a broad view of the capabilities of the FSW process for joining metals. This review article covers various work performed on friction stir welding, and the basics of the process and the fundamental aspects of operating an FSW. This includes a description of the different parameters that have been involved in this process. And also studied the material flow, forces, and other output responses, including defects, and strain rates that is produced.
