Investigation of Mechanical and Numerical Properties of Friction Stir Welding (FSW) for 3003 - H14 Aluminum Alloys

Abstract

In this paper, friction stir welding (FSW) has been focused on 3003 - H14Al alloy (AA).The welded specimens have been organized. Under dissimilar rotational rates of 1200, 1400 and 1600 RPM with feeding rate of welding 30 mm/min, mechanical features of joints like tensile strength and Micro-hardness have been investigated. In relation to measured fallouts, the machine-driven features of joints have been intensely influenced by dint of welding limitation. The finest con sequences of gained welding under 30 mm/min and 1400 RPM for welding velocity and rotating rate respectively. Accordingly, the efficiency gets 84% with respect to ultimate tensile strength (UTS) of parental metal. For 3003 - H14-W Aluminum alloy, this study has established the finite element simulation of FSW. Numerical simulations to identify the association of those factors with peak temperature have generated the investigations of specific heat, thermal conductivity and density. Simulation model has been verified with investigational consequences. The simulated consequences have agree with the experimentation consequences.
