Process Parameter Optimization for Tensile Strength for Plasma Arc Welding of SS304
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 6
Abstract
The Joining of the Austenitic Stainless Steels is often used in the pressure vessels, chemicals and processing industries. The mechanical properties at the weld bead should also fulfill requirement of applicable code. Several process parameters interact in the complex manner resulting in direct or indirect influence on the mechanical properties. It is necessary to find out the optimum process conditions which are capable of producing desired weld quality. Therefore to achieve the typical tensile strength in Plasma Arc Welding (PAW) is the primary objective of this study. The parameters Current (I), Voltage (V), Wire feed (Wf) were optimized using Taguchi Orthogonal Array and Analysis of Variance (ANOVA) is used for the analysis. The optimum parameters observed are Current: 230A; Voltage: 28V; Wire feed: 740mm/min resulting UTS of 687.35 MPa for SS304 of 6mm thickness..
