Title: Investigation of Mechanical Properties for Hybrid Joint of Aluminium to Polymer using Friction Stir Welding (FSW)
Abstract: This paper deals with investigating mechanical properties for friction stir welded hybrid joint (i.e. metal to polymer). The dissimilar joining of aluminium alloy (AA6061-T6) and polycarbonate with the plates of 3mm thickness was carried out by friction stir welding (FSW). The welding was done well below its melting temperature of base metal. This has come up with producing better weld joints. The influence of welding process parameters on strength of joint has been evaluated by means of tensile test. The tool rotational speeds were taken between 500 to 1400 rpm and tool traverse speeds were taken between 40 to 80 mm min–1. The joint welded at 500 rpm and 40 mm min-1 yielded a maximum tensile strength of 14.91MPa. The joint characteristics analyzed by means of microstructure testing in which weld zone revealed mechanical interlocking phenomenon between AA 6061 and PC. Microhardness measurement on the welding zone exhibited an irregular distribution of hardness at the welded joint.
