“…As tool rotational speed increases the grain size also increases which ultimately results in lower tensile strength [24]. FSW was performed on the milling machine at optimal process parameters such as tool rotational speed and welding speed of 1000 rpm and 60 mm/min respectively.…”

Aluminium alloys are welded using both tungsten inert gas welding (TIG) and friction stir welding (FSW). FSW doesn’t need any filler material and shielding gas which results in reduced degradation of the environment. In the present study, joints with FSW and TIG processes were compared in terms of microstructure, corrosion resistance, mechanical, and electrical properties. With a microstructural study, the average grain size of various regions was determined. Coarse grain increases the rate of exfoliation corrosion. The fine grain structure in the FSW stir zone increases the hardness. The coarse grains are a prerequisite for enhanced electrical conductivity. The coarse grains in the heat-affected zone and thermomechanically affected zones of FSW joints increase electrical conductivity. In the case of friction stir welded joints, there is an inverse relationship between hardness and electrical conductivity. As hardness increases, electrical conductivity decreases, and vice versa. Hence, in the case of FSW hardness test can be substituted by an electrical conductivity test. In the case of TIG, no relation was found between hardness and electrical conductivity. High Silicon content at the weld region of TIG significantly reduces electrical conductivity.

The AA1050 and AA6082 plates were used in producing dissimilar joint through friction stir welding (FSW) technique. The developed dissimilar joint was then subjected to multi-pass friction stir processing (FSP) technique. Various tests for the AA1050/AA6082 (AA1050 on the advancing side) and AA6082/AA1050 (AA6082 on the advancing side) joints were conducted on joints subjected to 1pass (1P) and 4pass (4P). The microstructural analysis showed that the increase in number of FSP passes resulted in a reduced grain size regardless of the of material position. The Vickers microhardness for AA1050/AA6082 FSPed joints increased towards AA6082 side while the microhardness for AA6082/AA1050 FSPed joints decreased towards the AA 1050 side regardless the number of the passes. The ultimate tensile strength (UTS) of AA1050/AA6082 joint increased with an increase in the number of passes while AA6082/AA1050 fluctuated between the specimens sampled from different locations of the FSPed joints.
