Numerical Simulation of the Effects of the Friction Stir Welding (FSW) for Ship Constructions

Aluminum alloys are relatively difficult to weld primarily due to aluminum’s high thermal conductivity and the formation of defects during welding including porosity and solidification cracking. Friction stir welding (FSW) is a relatively new joining process that has been demonstrated in a variety of metals, such as steel, titanium, lead, copper, and aluminum. In this paper, friction stir welding of aluminum alloys 5083-H112 plates was studied. The finite element analysis of variation of temperature and residual stresses in FSW of two similar simplifying geometry plates is performed with the ANSYS software. A good agreement between the computation and experimental results is obtained.
