Abstract

The current paper presents a numerical study on friction stir butt-welding of Aluminum alloy (AA6061-T6). The effect of pin geometry on the developed temperature and distributions of stresses at welding zone has been investigated. Seven tool geometries were simulated with coupled thermo-mechanical three-dimensional finite element models developed using Coupled Eulerian Lagrangian (CEL) method at ABAQUS® software V.6.14. The welding process was simulated in three stages, i.e. plunge, dwell and finally welding step in which the tool was traveled with constant linear speed. The results show that the tool geometry has a significant effect on the distribution of temperatures and stresses developed at the welded zone. Moreover, comparing the results of the developed models and those of the previous studies a good coherence was achiev
