In this research work, the virtual experiments were carried out to
investigate the influence of friction stir welding process (FSW) parameters on
output variables such as peak temperature and flow stress of friction stir
welding of aluminium alloy AA7075. The process parameters considered in this
investigation were rotational speed, traverse speed and shoulder diameter.
Friction stir welding simulations were performed using Hyper works (Hyper
weld). The results indicate that the FSW process parameters influence the
temperature distribution and flow stress during the process. It is found that
peak temperature increases and flow stress decreases with increase of
rotational speed with varying traverse speed and also found that the peak
temperature decreases and flow stress increases with increase of traverse speed
with varying rotational speeds. The temperature and flow stress distribution
increase with increase of tool shoulder diameter. - See more at:
