Experimental investigations on FSW of aa6082-t6 aluminum alloy

Abstract

The aim of the current work is to analyze the effect of rotational speed and the number of passes on the weld characteristics of FSWed AA6082-T6 joints. Twelve joints were produced by different combinations of FSW parameters, i.e., rotational speed and number of passes, for analyzing the influence of these parameters on quality parameters of the joints, i.e., tensile, hardness and microstructural properties. The results of a current study clearly show that studied input parameters significantly affect weld quality. Out of 12 joints fabricated in the study, the joint fabricated with two numbers of welding passes at 900 rpm rotational speed was observed to have the best mechanical properties.
