Finite element modeling of heat distribution and experimental study of butt friction stir welding of dissimilar metals

This research has been investigated the heat distribution in butt frictional stir welding for dissimilar metals by aluminum alloy of 1100 and copper using finite element analysis and experimental tests. As the temperature distributions in turbulent region directly effect the microstructure and mechanical properties¡ thus¡ determining of temperature distribution¡ during the process is very significant. Temperature distribution is simulated by ABAQUS software. To determine the thermal profile of the metal¡ the temperature has been recorded using thermocouples. The experimental data had a good agreement with the finite element analysis. As a result¡ other investigations can be done using the finite element method without conducting different experiments on thermal behavior of this kind of welding for other dissimilar metals under different conditions.
