Experimental and FEA Analysis of Aluminium Alloys for TIG Welding

Abstract

In the past, researchers did not consider welded joints in their finite element models. This could give large discrepancies to the mechanical characteristics of the structure and consequently would lead to inaccuracies in their predicted results. This paper attempts to present an appropriate way to model welded joints in a structure using the finite element method. Initially, two single-plates were developed in 3-dimensional finite element model and then welded. Later all three parts are assembled in CREO software. The two plates were joined together to form a single butt-joint of simple structure that involved gas tungsten arc welded (GTAW) joint. Mechanical characteristics of the butt-joint structure were determined experimentally and by finite element analysis and the predicted results were then compared with each other. FEA analysis is carried out in ANSYS 14.0 V software.
