Etude du soudage TIG de l’alliage d’aluminium 2024-T3

Abstract

Recent programs of aircraft design are characterized in terms of materials, by introducing weldable alloys as alternatives to the traditional technique of riveting, open the way to reduce weight and allow cost reductions in production and maintenance. Understanding the influence of various parameters of TIG welding process applied to the alloy 2024-T3 aluminum should help us to take into account the behavior in service of assemblies, from the design of structures. This work deals with the definition of a weldability operating field of the alloy studied and metallurgical and mechanical consequences of this assembly on the properties of the material.
