Numerical Stimulation of Welded Joints of Aa 5059 and Aa7079 During Friction Stir Welding Process

Abstract

Introduction: In this present studies 6mm, thick AA 5059 and AA 7079 plates are friction stir welded at different tool rotational speeds of 500, 750 and 1000 rpm, with a circular, taper cylinder and threaded taper cylinder tools.

Objective: The ANSYS model analysis is done in FSW process and the various temperature distributions during different travel time values are evaluated and find the optimal configuration is identified by the numerical simulation. 

Methods: The identified condition is applied to the friction stir welding process and experiments are carried out with the transverse speed of 40 mm/min of the tool.

Results: Vickers hardness test, microstructure analysis is performed on the welded material. Scanning Electron Microscopy (SEM) and Microhardness is done to identify the metallography studies.

Discussion: The findings from these investigations are presented and discussed.
