FSW Numerical Simulation of Aluminium Plates by Sysweld - Part I

Abstract

Friction Stir Welding (FSW) is one of the most effective solid state joining processes and it has numerous potential applications in many industries. The simulation process can provide the evolution of physical quantities such as temperature, metallurgical phase proportions, stress and strain which can be easily measured during welding. The numerical modelling requires the modelling of a complex interaction between thermal, metallurgical and mechanical phenomena. The aim of this paper is to describe the thermal-fluid simulation of FSW using the finite element method. In the theoretical part of the paper heating is provided by the material flow and contact condition between the tool and the welded material. The thermal-fluid results from the numerical simulation for aluminium alloy using SYSWELD are also presented in this paper.

FSW Numerical Simulation of Aluminium Plates by SYSWELD - Part II

“…The boundary conditions and finite element model with the results was presented in PART I of this article [2]. The result of the numerical solution of the thermal field with SYSWeld and the measurements taken with the camera are in a good agreement.…”

Process Parameters Optimization for Producing AA6061/TiB2 Composites by Friction Stir Processing

“…The temperatures developed during the FSW and FSP was below the melting point of material to be processed which avoids interfacial reactions and avoids defects like pin hole porosity, air inclusions. The FSW threedimensional model for Al alloy was developed and validated by researchers to build up the qualitative parameters [22,23].…”
