“…The dimensioned plates were then prepared for TIG welding. The double V-groove welding with 60°was used to produce the TIG-welded joint [22]. The filler metal used was ER5356 and this filler was used based on the recommendation from the literature [23].…”

“…Figures 4(a) and (b) show the pictures of the unprocessed (TIG welded joint) and processed specimens post tensile testing. The unprocessed joint specimens consistently failed at the center without any visible necking and this kind of failure characterizes the brittle failure [22]. The brittle failure is the phenomenon that is mostly influenced by the grain size and the presence of defects [37,39].…”

This paper reports on the experimental investigation of bending and tensile strength of the friction stir processed TIG-welded AA5083-H111 joint. The friction stir processed joint was studied comparatively with the TIG-welded joint (unprocessed joint). The TIG-welded joint was processed using a single-pass friction stir processing technique. The microstructural analysis revealed that the unprocessed joint was dominated with coarse grains while the refined grains dominated the friction stir processed joint. The unprocessed joint consistently failed at the center of the joint during tensile testing while the processed joint failed in different locations of the stir zone. The tensile strength of the unprocessed joint was found to be 47.4% to that of the base metal while that of the processed joint was found to be 76.5% to that of the base metal. The percentage elongation of the processed joint was found to be 82.4% to that of the base metal while that of the unprocessed joint was found to be 34.8% to that of the base metal. The bending failure mode of the processed and unprocessed joint was similar to that observed during tensile testing.

The aluminium alloys 5052 and 6082 are extensively used in manufacturing lighter structural members, having improved strength and resistance to corrosion. Magnesium (Mg) and Chromium (Cr) powder were the filler materials selected for enhanced corrosion protection properties in this investigation. Friction stir welding (FSW) process parameters viz., spindle speed, welding speed, shoulder penetration, the centre distance between the holes and filler ratio are used to forecast the minimum corrosion rate from different weld regions of AA5052-AA6082 dissimilar joints. Response surface methodology based on a central composite design was used to evolve the mathematical models and estimate dissimilar FSW joints’ corrosion rates. Response optimization shows that the minimum corrosion rate was achieved by the welding parameters of spindle speed 1000 rev/min, welding speed 125 mm/min, holes spacing of 2 mm and filler ratio 95% of Mg and 5% of Cr.

“…5 FSW is achieved successfully to weld similar and dissimilar materials. 6 Several investigators have fabricated the sound welds of dissimilar aluminum alloys such as AA7075/AA2024 7 ; AA5083/AA6082 8,9 ; and AA6061/AA8011. 10 Nowadays, the weld quality is further improved by imparting small-sized (micro/nano) particles in a particular concentration in the weld zone.…”

In this research, a defect-free dissimilar weld joint of AA7075-T6 and AA6061-T6 reinforced with Al2O3 nanoparticles was fabricated via friction stir welding (FSW). The influence of tool rotational speed (700, 900 and 1100 rpm), traverse speed (40, 50 and 60 mm/min) with varying volume fractions of Al2O3 nanoparticles (4%, 7% and 10%) on microstructural evolution and mechanical properties were investigated. The augmentation of various mechanical properties is based on the homogeneity of particle dispersion and grains refinement in the SZ of the FSWed joint. The findings revealed that the remarkable reduction in grain size in the SZ was observed owing to the incorporation of Al2O3 nanoparticles produces the pinning effect, which prevents the growth of grain boundaries by dynamic recrystallization (DRX). The increasing volume fraction of Al2O3 nanoparticles enhanced the mechanical properties such as tensile strength, % elongation and micro-hardness. Agglomeration of particles was observed in the SZ of the FSWed joints produced at lower tool rotational speed of 700 rpm and higher traverse speed of 60 mm/min due to unusual material flow. Homogenous particle dispersion and enhanced material mixing ensue at higher rotational speed of 1100 rpm and lower traverse speed of 40 mm/min exhibit higher tensile strength and micro-hardness.
