Abstract

Friction Stir Welding (FSW) is rather a recent technique that uses a non-consumable rotating welding tool to generate frictional heat and plastic deformation at the welding point while the material is in solid state. The principal advantages are lower distortion, absence of melt related defects and high joint strength. Tool design and material plays a vital role in addition to the important parameters like tool rotational speed, welding speed and axial force. This paper attempts to predict numerically both the temperature distribution during friction stir welding process of 6063 aluminum plates and the result in thermal residual stress by sequentially coupling the thermal histories into the mechanical model assuming of elastic-perfectly plastic metal behavior in accordance with the classical metal plasticity theory. The commercial code ANSYS 14 is used in Thermo mechanical modeling of FSW of aluminum 6063. Heat input from the tool shoulder and the tool pin are considered in the FEA model. A moving heat source with a heat distribution simulating the heat generated from the friction between the tool holder and the work piece is used in the heat transfer analysis.
