Scrutinize on friction stir channeling performance in dissimilar aluminum amalgams

This paper presents the parametric performance of channels formed in the experimental run of stir welding and its effect with respect to the traverse speed (TS) and rotary speed (RS) over the two dissimilar aluminium amalgams i.e., Al6082 and Al2024. In the experimentation it was observed that the parametric performance and effect of RS over channel area was inversely proportional to the TS with respect to valuated array of experimental data. During friction stir welding of dissimilar aluminium amalgams, geometry of void defects can be regulated to optimum with the systematic arrangement of processing parameters. The effect of TS and RS are indistinguishable throughout the cross sectional area of welded channel. The shape and size of produced friction stir channels were found to be strongly dependent on process parameters i.e., TS and RS. At constant RS of 1000 rpm the increase in TS from 50 mm /min to 100 mm/min changed the shape of channel from isosceles trapezium to triangular. Similar effect was observed for increase in RS.
