Abstract:Fully coupled thermo-mechanical model of friction stir welding is used
to analyze the effect of axial load on friction stir welding
process.Results indicate that the insufficient axial load leads to the
failure of the friction stir welding.The material deformation on the top
surface is affected by the rotation of both the welding pin and the
shoulder,which causes a larger material deformation on the top surface
than that near the bottom surface.The material deformation is not
symmetric to the welding line.The material deformation on the advancing
side is larger than that on the retreating side.The asymmetry of the
material deformation can be weakened with the increase of the axial
load. The maximum temperature of the welding plate during the friction
stir welding process is increased with the increase of the axial
load.The temperature field near the welding tool in the nugget zone can
become more homogeneous when the axial load is increased.
