    • Abstract
  • A new gas tungsten arc additive manufacturing process, with two homogeneous aluminum magnesium alloy wires synchronously feeding into same molten pool, was performed to manufacture high strength aluminum magnesium alloy component.Straight wall specimens were deposited by traditional single wire feeding and double-wire feeding gas tungsten arc additive manufacturing process, respectively. The difference in appearance size measurements, optical microscope, mechanical properties of the specimens were comparative studied in details. The results show the deposition rate of the double wire feeding mode is 2.08 times of the single wire feeding. The double wire feeding mode achieves finer grain. Moreover, the ultimate tensile strength of the double wire feeding mode reaches 71% of the 7A52 aluminum magnesium alloy. Compared with the single-wire feeding. the longitudinal ultimate tensile strength improved by 7% and the longitudinal elongation improved by 5% as well.
