Studies on Friction Stir Welding of Al-Cu-Li (AA2195) Alloy

Abstract:

For aerospace applications, Al-Cu-Li alloys are more attractive than conventional aluminum alloys due to their low density, high modulus and high strength. AA2195 is a third generation Al-Li alloy, developed with improved weldability. In this study, AA2195 alloy of 5mm thick sheets were welded by friction stir welding process (FSW). Tool rotational speed was varied from 400 rpm to 1000 rpm at constant travel speed of 60mm/min. Optimum tool rotation speed was identified and defect free weld coupons were processed with optimized parameter. Mechanical properties and micro structural characterization have been conducted on FSW welds.
