“…The average of the grey relational coefficients of the responses is termed as total relational grade (TGR) computed in a single response form for the data undertaken and is given in Table 8. The TGR values are now subjected to Analysis of variance (Table 9) using Yates algorithm [11]. The parameter rotational speed (A) is contributing to a tune of 83.58% in the achievement of all the responses, while the remaining two parameters are contributing insignificantly.…”

“…The geometry of the shoulder and the pin profile govern heat generation and material flow during welding [84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99]. The shoulder contributes to a large extent to heat input due to its size.…”

“…Similarly, Ji et al [91] reported that a halfscrewed pin also eliminated the cavity defect and increase the joint mechanical properties in comparison to a full-screwed pin. Venkatesh Kannan et al [92] also studied the influence of tool profile, i.e. cylindrical, cylindrical-threaded, squared, tapered, and stepped types, on the joint properties in dissimilar AA2024-AA5052 welds and reported that defect free joints were obtained by both newly designed stepped pin tool and cylindrical-threaded pin tool.…”

Numerous industrial applications, particularly those in the transport industry, require the joining of dissimilar materials which offers considerable benefits in terms of low cost, design flexibility, and weight reduction for overall structures. The problems associated with conventional fusion welding processes have stimulated researchers in recent years to develop new joining methods for dissimilar materials which are particularly difficult to join. Friction stir welding (FSW) originally developed for joining difficult-to-weld Al-alloys and FSSW (a variant of FSW for spot welding) have exhibited great potential for obtaining sound joints in various dissimilar alloy systems in different configurations namely butt-, lap-and spot-welding, particularly in dissimilar Al-alloys systems with different properties, which are very difficult to weld using conventional fusion welding techniques. A major difficulty in joining dissimilar Alalloys by FSW/FSSW lies in the discontinuity in mechanical and technological properties (such as high temperature strength, plastic deformation capacity, viscosity, etc.) of the materials to be welded across the abutting surfaces. This discontinuity as well as inherent asymmetry in heat generation and material flow of FWS/FSSW processes causes a higher asymmetry in materials flow behavior in dissimilar welding. However, it is relatively easier to implement the FSW/FSSW process to dissimilar Al-alloys in contrast to FSW of dissimilar materials combinations with very differing properties, such as Al-alloy to Mg-alloy or Al-alloy to steel.

AA5052 bead-on-plate processing has been achieved by the friction stir processing (FSP) technique to examine the manipulation of process parameters. It also improved the base metal surfaces to analyze the microstructure. The tool spinning speed, traverse speed, and axial load were preferred to investigate the effect of friction stir bead-on-plate processing on the tensile strength qualities and microhardness in AA5052. An optical microscope was used to dissect the fabricated processed zones of the microstructure. By using the design of the experiment, the orthogonal array of the L9 Taguchi method was used to construct the processing experiments. The analysis of variance and the signal-to-noise ratio methods were employed to identify the optimum unification of process parameters and the significant benefaction of a specific parameter on the responses. The outcomes showed that the tool spinning speed was the principal factor affecting the characteristics of tensile strength and microhardness, succeeded by the traverse speed and axial load. The intermetallic compound layer had formed during the processing under specified conditions. This examination revealed that the optimum parameters could intensify the mechanical behaviour of AA5052.
