“…Harachai er al. [206] use RSM based on the Box-Behnken design to investigate the appropriate process parameters in friction stir welding between AA6061-T6 and AA5083 by finding that the better combination is 777 rpm/44 mm/min. Umamaheswarrao [207] identifies the best friction stir welding process parameters for alloys AA6061-AA7075 using a multi-criteria decision-making technique [208], namely the Desirability Function Analysis.…”

Friction Stir Welding is a suitable solid-state joining technology to connect dissimilar materials. To produce an effective joint, a phase of optimization is required which leads to the definition of process parameters such as pin geometry, tool rotational speed, rotation direction, welding speed, thickness of the sheets or tool tilt angle. The aim of this review is to present a complete and detailed frame of the main process parameters and their effect on the final performance of a friction stir welded joint in terms of mechanical properties and microstructure. Attention was focused in particular on the connection between different aluminum alloys. Moreover, the experimental results were correlated to the development and the applications of tools which can be effectively used in the design of the manufacturing process such as finite element analyses, artificial neural networks, and statistical studies. The review also aims to be a point of reference to identify the best combinations of process parameters based on the dissimilar aluminum to be joined.

“…As stated by P. Kah and Marikainen, as well as The Welding Institute (TWI), the progress of the FSW approach has typically become obvious in the domains of shipbuilding, railways, aerospace, and land transportation [18]. Further uses have also been identified [33][34][35][36][37][38][39][40]. FSW can be used to effectively weld panels (sides, bulkheads, decks, and floors), landing pads for helicopters, offshore accommodations, hulls and constructions, and containers for refrigeration plants.…”

Friction Stir Welding (FSW) is an innovative and reliable welding technique. Since this method is environmentally beneficial, it has received much attention and development over the past few decades. This study aims to revise the conceptual facts of FSW and evaluate the most recent improvements and developments in its applications. This review also assesses the influences of design parameters such as rotational and welding speeds on weld quality and joint efficiency. Existing challenges associated with applying FSW in various contexts, as well as the potential advantages that might lead to further study and broader FSW applications, are addressed. It has been concluded that FSW allows for optimising the rotating speed based on the preferred welding speed to achieve the greatest tensile strength in the welded materials. Despite FSW being established as effective in laboratory and small-scale applications, utilising FSW for large structures poses challenges. These challenges include maintaining consistent weld quality, controlling heat dissipation, and ensuring joint integrity during FSW. Consequently, further research is required to resolve these challenges and make FSW a promising welding method in contemporary production sectors.

“…Optimal parameters of the welding process with the Taguchi method were analyzed by signal-to-noise ratio analysis; S/N analyzed the main effect of the factor and S/N Ratio values on the UTS values. Larger-the-better [21][22][23][24][25] values were determined. The results of the analysis are as follows.…”

This study investigated the ultimate tensile strength (UTS) of dissimilar welding processes between Ti-4V-6Al titanium alloys with SS304 stainless steel by gas tungsten arc welding (GTAW) process. The intermetallic compounds of the welds were investigated by X-ray diffraction, and the Taguchi method was used in the experimental design. The welding process parameters are welding current (A), welding speeds (B), and Wire feeds (C). ANOVA analysed the S/N ratio of ultimate tensile strength to determine the optimal parameters for statistically significant factors. Analyse for process parameters on the response and the level of the indispensability factor, as well as predict and regression model for optimal tensile strength. The investigation revealed that the optimum parameters were A1B2C2, and the ultimate tensile strength was 285MPa. The ANOVA analysis found that welding current and welding speeds had significance on the ultimate tensile strength of the workpiece at a 95% confidence level. The investigation of intermetallic compounds of the welds with X-ray diffraction technical found that increased welding current tended to cause Ti3Cu and Fe4Cu3 compounds and affected the tensile strength of the weld to decrease.
