Taguchi Based Mechanical Property Optimization Of As Weld Al-65032 Alloy Using Tig Welding

Abstract

In recent days, light materials like aluminum alloys are becoming more prominent in real world.In this paper, the parametric design of aluminum alloy (AL 65032) is carried out for the optimum mechanical properties (UTS, 0.2% proof stress, percentage elongation) using Taguchi techniques. This paper considered only for weld conditions. Hence the parametric design is carried out for TIG welding with as weld condition and with control parameters gas pressure, current, groove angle and preheat. Three levels are considered for the control parameters based on the preliminary tests and analysis is carried out with L-9 orthogonal array.

Optimization of Bead Geometry during Tungsten Inert Gas Welding Using Grey Relational and Finite Element Analysis

“…Research showed that an optimal welding speed could produce a joint with high mechanical strength, excellent microstructure, and good morphology [5]. Eshwar Materials 2023, 16, 3732 2 of 22 et al (2014) found that the input parameter has a substantial role in determining the weld quality, which primarily includes bead width and height, and penetrating the area, thermal, and residual stresses, resulting in minimizing the life of a weld joint [6]. Researchers have tried to work on different welding processes regarding weld bead geometry, temperature, and stress fields.…”
