| Abstract: | Fusion welding of cast A319 (Al-Si-Cu) alloy will lead to many problems including porosity, micro-fissuring, and hot cracking.
Friction Stir Welding (FSW) can be used to weld A319 alloy without these defects. In this investigation, an attempt has been
made to study the effect of FSW process parameters on the tensile strength of A319 alloy welded joints. Joints were made using
different combinations of tool rotation speed, welding speed, and axial force, each at four levels. The quality of weld zone
was analyzed using macrostructure and microstructure analysis. Tensile strength of the joints were evaluated and correlated
with the weld zone microstructure. The joint fabricated with a 1200 rpm tool rotation speed, 40 mm/min welding speed, and
4 kN axial force showed superior tensile strength compared with the other joints. |
