“…With every factor considered comprehensively, it can be concluded that plastic properties, including percent elongation and ratio of reduction in area, play a more important role in tensile properties than tensile strength because all the values of tensile strength in these experiments are more than 300 MPa, which is high enough in most applications. Plastic properties restrict the further improvement of mechanical properties of AA 5456 aluminum alloy [4]. Therefore, take 0.6 as the optimal parameter of ψ when plastic properties are at maximum.…”

“…Al-Mg 5xxx series contain more than 3.0% magnesium, while the vaporization of alloying elements will occur during welding fabrication. This vaporization loss may reduce the mechanical properties of welded joints by affecting the chemical compositions of molten pool [4][5][6]. In order to enhance the weld quality of Al-Mg alloys, metallurgical advantages of welds produced by high-frequency pulsed and magnetic arc oscillation methods are frequently investigated, including stirring effect on molten pool, refinement of grains, reduction of distortion, and control of segregation [7][8][9].…”

Abstract:Tensile properties optimization of AA 5456 aluminum alloy was carried out with hybrid ultrasonic frequency pulsed variable polarity gas tungsten arc wending (HPVP-GTAW). An orthogonal method was employed to conduct the experiments, and the tensile properties of AA 5456 aluminum alloy welded joints were measured and analyzed. Regression models were developed based on the least square estimation by taking tensile strength, yield strength, percent elongation, and ratio of reduction in area as response functions of variable polarity frequency f L , pulse frequency f H and a dimensionless parameter ψ, which were calculated by background current I b , peak current I p , and pulse duration δ, respectively. The developed regression equations were checked for validity by coefficient of correlation r 2 and confirmatory experiments. Optimum parameters of HPVP-GTAW were achieved through the discussion on response surfaces and contour plots drawn using the regression equations.
