A finite element model of radar cooling board friction stir welding process was built in ANSYS software based on an instantaneous relative linear velocity heat source model. Temporal and spatial temperature distribution disciplinarians were analyzed; results show that the peak temperature is lower than the base material melting point, as a result there is no material melt during the welding process. Temperatures change disciplinarily with the progress of welding process at each point.

In In this work the methods are developed to perform simulations of the friction stir welding process using the ANSYS software working scheme, developing multiphysics couplings between computational fluid dynamics tools to Model the viscoplastic effect of the fluidity of the material when it is stirred by means of a solid tool modeled in the Transient Structure application that allows calculating the thermo-mechanical effects of the study process. The results show the validations corresponding to the modeled and experimentally performed analysis showing a lot of reliability in the proposed method. The torque reached in the process is maintained in the ranges of 14 Nm, the maximum temperature reached in the process was 540°C, this being 78.3% of the melting temperature of the material studied, having an adequate range for these studies.

This paper introduces the analysis of a trailer structure made of 6063-T5 aluminum alloy using the Friction Stir-Welding process. The base material and the welded joint were characterized by tension tests. The loads for the structural analysis were obtained from field tests where stresses were measured on critical points at a 2.73 m long 0.95 m width trailer while it was driven on an unpaved road. The stresses on the whole trailer were found by using a finite element model, where the joint with the maximum stresses was identified. This joint was constructed with a tubular structural element using Friction Stir Welding and was evaluated by bending tests. Using the impact factor obtained from the field test, fatigue analysis was performed on the welded joint. It was found that the strength of the joint was sufficient to carry the loads on the trailer.

This review paper will discuss about the joining process of Aluminium 3D printing materials by using friction stir welding process. Currently, the studies on the joining of 3D printing materials by friction stir welding are very limited. Through this review, the joining materials characteristics such as weld efficiency, hardness and microstructure after friction stir welding process will be discussed to identify the behavior of weld joint materials. Understanding the friction stir welding process on 3D printing materials is importance in order to support the future advancement of 3D printing technology in terms of 3D printing part repairing activity and the secondary process such as the joining of 3D printing parts. In this paper, the fundamental concept of friction stir welding and powder bed fusion 3D printing is discussed. At the end of the review, the summary of friction stir welding process on Aluminium 3D printing materials concluded that the joining process is feasible to weld the materials with joint efficiency 83.3% and modify the base material characteristic of the 3D printing materials.

The present work focused on welding aluminium alloy 5083 using the friction stir welding process. Suitable welding process parameters were identified to fabricate a defect-free butt joint with a tool rotational speed of 1600 rpm, traverse speed of 20 mm/min and tilt angle of 3°. The microstructure at the nugget zone, thermo mechanically affected zone, heat-affected zone and base metal zone are examined. Mechanical properties of the weldment exhibited promising results with an average joint efficiency and hardness of 75.70% and 94.0 ± 5.0 vickers hardness, respectively. Fractography revealed ductile mode of failure in base and weld metal tensile samples. Furthermore, a 3D thermomechanical finite element model was utilized to simulate the friction stir welding process using the selected process parameters. Arbitrary Lagrangian–Eulerian-based model aided in predicting residual stress distributions and thermal history during the friction stir welding process.

The aim of this study was to investigate the crystallinity changes and degradation of polypropylene due to heat generated by friction stir welding, i.e., heat generated by friction between the rotation tool and the welded materials. The tool pin was rotated at 620 rpm in the welding process. The travelling speed was varied between 7.3 mm/minute and 13 mm/minute. A cylindrical tool pin, 4.5 mm in diameter and 5.7 mm in length, was used in this experiment. The shoulder dimension was 18 mm in diameter and 90 mm in length. A conventional milling machine was used in the friction stir welding process. The crystallinity test was carried out with X-ray diffraction, hardness was observed using a Shore Type-D durometer, and polymer degradation data was obtained by thermogravimetry analysis. The areas compared were base material, weld nugget area, and thermomechanical affected zone. The results showed that there was a change in the percentage of crystallinity in areas that had undergone friction stir welding, and that the change was inversely proportional to the traveling rate of the friction stir welding process. The friction stir welding process was affected by the initial degradation temperature and hardness property of the polypropylene. This result shows that it is possible to choose specific parameters of friction stir welding in order to obtain good weld joint properties.
