Abstract |
|
In this study Tungsten Inert Gas (TIG) process parameters are optimized by using Taguchi method. Process parameters considered for the study are Gas flow rate, Welding current and Pulse frequency. AA7075 alloy has very unique properties of light weight and corrosion resistance and due to this it becomes very interesting metal in the field of engineering. AA7075 plate of rectangular shape has been used for machining operation. Performance of TIG machine has been measured by ultimate tensile strength (UTS). In Taguchi method L9 orthogonal array has been selected. The analysis of variance (ANOVA) has been used to determine effect of each parameter on ultimate tensile strength and micro hardness so Finally, the confirmation test has been carried out to compare the predicted value of tensile strength and micro hardness with the experimental value. |
