WELDABILITY AND FORMABILITY CHARACTERISTICS OF TAILOR WELDED BLANK OF ALUMINIUM ALLOY AA1050

Abstract

A promising approach to reduce manufacturing costs, decrease vehicle weight, and improve the quality of automotive body components is through the use of Tailor-Welded Blanks. This term refers to blanks where multiple sheets of material are welded together to create a single blank prior to the forming process. The welding process creates formability concerns in a traditional forming process due to material property changes in the weld and in the heat-affected zone adjacent to the weld. The purpose of this study is to optimize the welding parameters by the Design of experiments; Taguchi approach, Regression model and ANOVA are used. Welded the specimens by GTAW process considering the Optimized parameters and conducted Limit Dome Height test. During the deep drawing process of these specimens, the differences of weld-line movement and thickness strain distribution are investigated by experiment and analysis The main aim of the work is to investigate the effect of weld conditions viz.,...
