Correlating Tensile Strength & Peak Temperatures for Magnesium Alloy AZ91 during Friction Stir Welding Using Varied Tool Geometries & FEA Tool

13 pagesPublished: August 5, 2017

Abstract

Magnesium & its alloys are flammable for conventional fusion welding process. This adverse effect can be eliminated by a non-fusion solid state welding process, established by The Welding Institute (TWI) in 1991, called friction stir welding (FSW). This is applied in this investigation for joining two plates together by using non-consumable tools (three pin profiles) between two abutting plates of magnesium alloy AZ91 having 6 mm thickness. FSW process joins the plates with certain advantages such as low distortion, no shielding gas required, fine recrystallized microstructure, no fumes liberated during the process, etc. In Friction stir welding, process parameters such as welding speed, tool rotation speed, tool dimensions and axial force play an important role during the process. In the present work, the 6 mm thick plates of the said alloy are welded at traverse speed of 28 mm/min to 56 mm/min with tool rotation speed ranging from 710 rpm to 1400 rpm. Tensile strength testing & simulation of peak temperatures has been carried out for establishing correlationship between best parameters from the selected ones with temperature profiles obtained by those parameters for giving optimum structure-property relationship using different pin profiles.

Keyphrases: FSW, Magnesium Alloy AZ91, Peak Temperature Simulation, tensile strength, Tool Pin Profile
