Abstract

El objetivo del presente trabajo es evaluar la variación de los parámetros (amperaje y flujo de gas argón) del proceso de soldadura bajo protección gaseosa con electrodo de tungsteno TIG en los cambios morfológicos de la aleación AW5086 y el incremento de las propiedades mecánicas (resistencia a la tracción y dureza). Aquí se observó que, dentro de las corridas experimentales realizadas, la de mejor comportamiento fue posible que se dieran las mejores condiciones en la frontera de los granos y en su interior para garantizar las mejores propiedades mecánicas. Lo anterior lo evidenció una morfología donde se observó una distribución más ventajosa del microconstituyentedesiliciuro de magnesio Mg2Si.

Palabras claves: soldadura, TIG, parámetros, morfología, aluminio AW5086.

Abstract

The objective of this work is to evaluate the parameters (amperage and argon gas flow) of the welding process by gas protection using tungsten electrode TIG in the morphological changes of the aluminum alloy AW5086 and the increase of its mechanical properties (tensile resistance and harden). The best variant with 150 A and 8 L/min was the 1 because with this amperage and flew was possible to obtain in the frontier, as well as, inside of the grain the bests mechanical properties. All of this was the evidence of the morphology where the best distribution of the microcompouse of the magnesium slicer Mg2Si was observed.

Key words: welding, TIG, parameters, morphology, aluminum AW5086.
