Abstract

Friction Stir Welding (FSW) procedure is utilized for joining material, for example, aluminum, copper, magnesium and so on. It is a clean, environment-accommodating, and non-harmful process as it is neither accompanied by a circular segment arrangement and radiation nor toxic gas discharge. It has low warmth input and no weld finishing costs (Shukla and Shah, 2010). The paper examines the utilization of Taguchi method for augmenting tensile strength of friction stir welded Al 6061 alloy. The impact of process parameters on rigidity of welded joints and signal-tonoise ratio of robust design are assessed. The various process parameters, such as tool rotation speed, welding speed, tool design, axial load, etc., play a critical role in obtaining better and defect-free joints. We considered the geometry of tool of the welding joint separated from other parameters like temperature and pressure. The impact of welding parameters on the greatest temperature improvement has been studied. We used AA6061 similar material for flow stress, temperature and pressure analysis with Hyper works 9.0.

Introduction

Friction Stir Welding (FSW) innovation helps in joining aluminum sheets without material preheating. The welding procedure happens by a rotating FSW tool. FSW is a revolutionary solid state welding technique invented at The Welding Institute (TWI) in 1991 (Shukla and Shah, 2010). The FSW process operates below the solidus temperature of the metals being joined and hence no melting takes place during the process. As FSW process is a solid-state process, it requires low heat input, and it results in low distortion, no macro segregation and a finely re-crystallized microstructure (Mishra and Mahoney, 2007).
