“…Welding AA 5083 and AA 6082 alloys attracted different previous works 16 , 17 . Bo Wang et al modifies the ER 4043 filler electrode by adding Ti and Sr to improve the mechanical properties of AA 6082 weldments using GTAW 16 . They concluded that the addition of the Ti and Sr together improves the welded zone's microstructure and leads to the enhancement of mechanical properties.…”

Welding of dissimilar aluminum alloys has been widely used in many industrial applications. However, the selection of filler type still attracts significant interest in the welding research area. The present work concerns the effect of filler metal on the microstructure and corrosion of weld joints of dissimilar aluminum alloys. AA 5083 and AA 6082 alloys were welded by tungsten inert gas welding (GTAW) using filler metals ER 4043 and ER 5356. The microstructure observations and the corrosion test of the weld joints were carried out. Solidification cracks were observed in the ER 4043 weld zone, whereas defect-free joints were obtained using a mix filler welding process. A galvanic corrosion was observed on the boundary between the filler rod ER 4043 weld zone and AA 5083 base alloy. From the corrosion standpoint of view, the using of ER 4043 electrodes is not preferred for welding 5000 series aluminum alloys, whereas ER 5356 filler electrode is more favorable than ER 4043 filler electrode either for dissimilar welding of AA 5083 and AA 6082 alloys or individual welding of both aluminum alloys. No galvanic corrosion is observed between ER 4043 fillers and AA 6082 base alloy.

“…the alloy has good weldability and cold formability. it has a medium to high strength as well as comparable fatigue strength [6]. AA5083 grade aluminum alloys have trace amounts of manganese and chromium alloyed with magnesium which make them highly resistant to attack by seawater and industrial chemicals [7] "Which are particularly capable of retaining high degree of strength after welding.…”

OptimizatiOn Of GtaW prOcess parameters Of Dissimilar al-mg allOys fOr enhanceD JOint strenGth -taGuchi apprOach the tungsten inert Gas (tiG) welding processes one of the prevalent methods used for welding aluminum alloys. tiG welding is most commonly used due to its superiority in welding less dense materials. the most prevalent issues encountered with tiG welding aluminium alloys are porosity creation and cracking due to solidification, both of which result in lower mechanical properties. because of the metal's susceptibility to heat input, this occurs. the current work is the result of a desire to improve the mechanical properties of dissimilar aluminium metals: AA5052-h32 & AA5083-h111. the process parameters of tiG welding are optimized towards eliminating the previously discussed failure scenarios. various optimization techniques exist towards obtaining optimizing processes such as response Surface methodology (rSm), Genetic Algorithm (GA), Artificial neutral network (Ann), Flower pollination algorithm, taguchi method etc, the taguchi method was chosen for the optimization of process parameters due to its inherent nature of solving problems of singular variance. the optimal parameters combination was determined i.e. welding current at 170 A, filler rod diameter 2.4 mm and Gas flow rate of 11 lpm. the optimized input parameter was used to tiG weld the confirmation specimen which are further investigated for mechanical and metallurgical characterizations. the parameters were optimized and the results indicate that the input current was found to be the most contributing towards improving mechanical properties over all the process parameters.
