Study of Superioring of a Seal Soldered by Tig Process of the Aluminum League 6061

摘要

The aim of this work was to verify the mechanical behavior of a Gas Inert Tungsten (TIG) welded joint of a 6061 aluminum alloy, after aging and super-aging thermal treatments. The characteristics of aluminum allow diversified applications, which contributes as one of the most used metals in the world. Being a lightweight, durable and sturdy material, it shows excellent performance and superior properties in most applications. Brazil is the eleventh primary aluminum producer, preceded by China, Russia, Canada, the United Arab Emirates, India, Australia, the United States, Norway, Bahrain and Saudi Arabia. The specific objectives were to obtain welded joints in aluminum by TIG process, performing the thermal treatments of aging and super-aging, metallography/macrography tests of welded joints, microhardness test of treated and untreated joints, and analysis of the results. The methodology used in the analysis of the samples was by the techniques of Metalografia and Microhardness.
