Description: Friction stir welding (FSW) is a new and promising welding process that can produce low-cost and high-quality joints of heat-treatable aluminum alloys because it does not need consumable ﬁller materials and can eliminate some welding defects such as crack and porosity. In this paper the effect of welding speed and tool pin profile on FSP zone formation in A319 alloy has been studied. Different tool pin profiles are used to fabricate the welding joints. Those profiles are round, round taper, square and treaded, and the Finite Element Analysis (FEA) process coupled field analysis on different tool pin profiles to verify the temperature distribution, thermal flux, gradient and stresses have been studied. The experimental results showed that thermal gradient is less for round cutting tool and it was found around 577.4 K/mm and thermal flux is also less which around 7.507 W/mm2.
