ANTUNEZ-QUESADA, Jorge et al. Evaluation of the proceeding by gas Argon in the aluminum AW5086. Ingeniería Mecánica [online]. 2017, vol.20, n.1, pp. 45-50. ISSN 1815-5944.

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.
