Dissimilar Steel Alloys Welding Joint Process Parameters Optimization

Nowadays, the customer satisfaction is the major responsibilities and duties of the organizations management. In this research paper we find the best optimized welding joints with process parameters such as: welding current, welding voltage and gas flow rate for the best tensile strength and micro-hardness of the welding joints. Taguchi method which reduces the variation in process through design of experiments has been used. In this study presents an efficient method for determining the optimal Gas Metal Arc Welding parameters for increasing the weld ability of Stainless Steel 202 & Stainless Steel 304 under varying condition through the use of Taguchi parameter process. The study shows that the optimum parameters for tensile strength are found when Welding Voltage is at 18 Volts, Welding Current at 50 Amps and Gas Flow Rate at 15 L/min and optimum parameters for hardness are found when Gas Flow Rate is at 15 L/min, Welding Current at 75 Amps and Welding Voltage at 18 Volts. From ANOVA it is found that welding parameters significantly affects the weld quality of Stainless Steel 202 and Stainless Steel 304. Citation: Ashwani, Kuldeep Singh.
