To Analyze the Impact of Process Parameters Such as Gas Flow Rate and Welding Current on Tensile Strength and Hardness of TIG Welding for Dissimilar Steel Metals (KEY IJP************914)
Abstract
The aim of this research work is to predict and optimize TIG welding of some economically important dissimilar materials in industry through applying as a DOE approach to design the experiments. This can be achieved by controlling selected welding parameters as per ASME Section IX for; gas flow rate and welding current to relate the ultimate tensile strength and Hardness to the selected input welding parameters. The dissimilar materials studied in this work are Stainless steel 304 and SA-515 (Grade-60). The effect of different gas flow rate (8, 10 and 12 Litmin), different welding current (80, 100 and 120 Amp) on ultimate tensile strength and Hardness of dissimilar welding, are used to find out the significance of input parameter on output by using DOE method. The Analysis of Variance (ANOVA) technique is used for Optimization.Keywords: Ultimate tensile strength, Analysis of object (ANSYS), Tungsten inert gas Welding (TIG), Analysis of Variance (ANOVA).
