“…In addition, the FSW process proved the effectiveness of heat input by producing metallurgical bonding grain in the stir zone, which resulted from material flow mixing. Therefore, it was possible to get a relatively sound welding result with welding settings of the high rotational speed (2085 rpm) used to generate the proper amount of heat input from mechanical mixing and the associated high welding speed (762mm/min) [56]. Therefore, welding parameters such as rotating speed, tool penetration, and welding speed are critical to a successful welded joint.…”

“…Welding speed is the following list of factors influencing the weldment product's properties [62]. Welding and rotational speed contribute to a significant responsible impact on heat generation during the FSW process [56]. The high temperature reached during the FSW process relies on the welding speed value [41].…”

Friction stir welding (FSW) has an advanced technique in solid-state conditions that joins from different materials compared to the fusion welding process and is eco-friendly. This ignificant advancement involves aluminium (Al) alloys which facilitate the FSW of distinguished flow patterns in the weld zone. Technically, heat energy and stirred material resulted in softening areas, affecting joint efficiency, mechanical properties, and metallurgical characterisation. This paper has concerns comprehensively covering and summarising the development and application of the topic in different aspects of the performance and quality of the FSW welded joint. The proper tools can create sufficient heat under the shoulder for excellent performance to deal with the welding parameter. All these tools have their literature and journal, which extensive discussion.Furthermore, alloy positioning, defect formation,rotational speed and transverse feed are essential analytical tools for FSW to control the significant weld quality. Furthermore, the mechanical properties associated with microstructural evolution highly dependent on welding technique have remarkably contributed to product development. Finally, a previous study has shown the interest in the topic to enhance the knowledge for further investigation with emerging technology for future recommendations in the FSW discipline.

“…The unique properties of copper and its guides have advantages such as good electrical and thermal conductivity, ductility, and corrosion resistance. Copper alloy is the industrial choice as a product material because it can produce good, precise, and complex processes [2]. Industrial options use non-ferrous materials such as brass, which have the main elements copper and zinc because they have good mechanical properties, excellent machinability, and corrosion resistance [3].…”

Brass alloys contain the dangerous element lead. Material engineering is carried out to reduce the lead element in brass alloys and add nickel elements as a substitute for lead elements by the casting process. The phenomenon analyzed in this study explains comparing the accuracy level of OES and EDX test results on nickel dissolution in brass casting, especially in adding nickel elements. So that researchers can compare the decrease in the percentage of nickel element composition in the OES test results. At the same time, there is an increase in nickel element composition in the EDX test results. The brass dissolution process uses an electric furnace with an initial temperature of 526 °C. Elemental nickel was introduced into brass solution and dissolved elemental nickel at 978 °C for 120 min for a variation of 1 %, 2 %, 3 %, and for 180 min for a variation of 4 %. The composition of alloying elements is tested using OES and EDX. The dissolution process of brass with the addition of nickel elements tested with OES decreased from 1 % nickel elements to 0.650 %, 2 % to 1.630 %, 3 % to 2.046 %, and 4 % to 2.810 %. Meanwhile, from the EDX test results, there was an increase in the composition of nickel elements from nickel 1 % to 1.41 %, 2 % to 2.57 %, 3 % to 3.41 %, and 4 % to 4.49 %. Brass alloys with nickel elements added decreased due to slag produced during the dissolution process of nickel elements in molten brass from the test results using OES. EDX testing results in an increase in the percentage of nickel elemental composition. The results of the OES test validation of the mechanical properties of adding nickel elements to brass alloys can be considered because the material's strength is still under the reference UNS C89550. This research contribution resulted in an effective and efficient test method with OES to analyze the elemental composition in brass alloys to which nickel elements have been added

In this study a new ceramics tools with different groove distributions were designed and manufactured in order to enrich technological storage of joining thinwall structures and obtain sound joint with high quality of Alclad AA2024-T3 alloy of 0.5 mm in thickness. Four types of tools were tested, without grooves, with 1, 2 and 6 grooves. The tools are made of two materials. The straight shank is made from tungsten carbide and tool body made from ceramics strengthened with whiskers. The influence of technological parameters on the strength of FSW joints was tested by the Response Surface Methodology (RSM) and Analysis of Variance (ANOVA) method. The least durable weld is produced by a tool without grooves. The single and double flute tool produces a good quality weld over a wide range of tool speeds. It has been shown that the grooves on the tool shoulder significantly affect the quality of the obtained FSW joint.
