“…In this process, the joining of workpieces is accomplished by the FSW tool, [11] which creates the weld joint by plastic process [3] [10]. The technique of FSW improves the strength characteristics of the weld joint; however, the corrosion behaviour of FSW joints are a critical aspect of concern, which needs to be studied [4] [9]. In this regard corrosion characterization of FSW weld joints of dissimilar aluminium alloys is studied in this research for a prospectus in real-time engineering applications…”

Friction Stir Welding is a solid state welding processused in aerospace, automobile and machine tool industry. However, corrosion of the friction stir weld zones is still a major drawback that needs to be addressed immediately; hence the current work focuses on the corrosion characterization of the friction stir weld joints of dissimilar aluminium alloy. In the present research, friction stir welding is carried out at different set of parametric conditions and the weld joints are characterized for weight loss corrosion in sodium chloride saline medium. The friction stir weld joints of dissimilar aluminium alloys are obtained using three sets of process parameters viz., tool profiles of straight cylinder, taper cylinder, and straight triangular; tool rotational speed of 800 rpm, 1000 rpm, and 1200 rpm; tool feed rate of 100 mm/min, 120 mm/min, and 140 mm/min; tool offset of 0.5 mm, 0 mm, and-0.5 mm. The corrosion characterization is carried out for friction stir weld joint using immersion tests. The results give an overview of the variation in the corrosion with time, and the effect of process parameters on the corrosion behavior of weld joints.

“…When these materials are utilised to build various structural components, the overall weight is reduced, which improves fuel economy and reduces pollution [5,6]. Due to the development of high temperatures, the combining of different aluminium alloys using the traditional fusion welding process leads in the formation of intermetallic compounds and numerous welding related flaws [7][8][9].…”

The course of contact mix welding is quick acquiring conspicuousness in aviation, marine and car industry because of its benefits as far as mechanical strength, effect and hardness characteristics. There is as yet a requirement for sure fire consideration from the exploration local area to erosion in grating mix welding zones, hence the work introduced here centres around the consumption portrayal of the grinding mix weld divergent aluminium composite. This study looks into friction stir welding under various parametric settings and shows how corrosion happens in a sodium chloride electrolytic media under potentio-dynamic conditions. The friction stir weld joints of dissimilar alloys aluminium are constructed using three sets of parameters. Straight cylinder, taper cylinder, and straight triangular tool profiles; tool rotational speeds of 800, 1000, and 1200 rpm; tool feed rates of 100, 120, and 140 mm/min; and tool offsets of 0.5, 0 mm, and -1.5 mm. The corrosion current (Icorr) reduces as tool rotating speed increases up to 1200 rpm, after which it slightly increases due to the creation of ridges all around the periphery of the friction stir weld area.

“…Aluminum alloy AA 2014-T6 of 5 mm thickness is friction stir welded by changing pin profile geometries and other factors to state the influences of the chosen experimental condition on tensile properties and microstructure are exhibited utilizing response surface methods [18]. Taguchi design utilized to optimize a set of friction stir welding parameters in terms of total crack energy, crack initiation energy, and crack propagation energy in weldments, [19]. Ismail et al, [20] presented full penetration FSW of 6063 aluminum pipes and gathered that a high tool rotational speed of 1500 rpm and a welding speed of 144 mm/min produced defect-free welds.…”

In this work, the Taguchi technique has been applied to optimize the welding parameters to detect the better mechanical attributes of friction stir welded AA6061, AA1050, AA5049, and AA5754 joints. L16 orthogonal array is used by considering the welding parameters, such as rotational speed, transverse speed, and tool pin profile. The best welding parameters for the greatest tensile strength and hardness of the joints were detected by studying the signal/noise (S/N) ratio and analysis of variance (ANOVA) results. The optimum levels for tensile strength were found to be 800 rpm rotational speed , materials 1050-H24 aluminum alloy, 25 mm/min transverse speed and pin profile is conical .Also, the optimal levels for hardness were found to be 600 rpm rotational speed, materials 1050-H24 aluminum alloy, 32 mm/min transverse speed and pin profile is conical . Besides, the fractured surface microstructure was examined of the friction stir welded joints.
