Abstract :

Welding is a manufacturing process, which is carried out for joining of metals by Tungsten Inert Gas (TIG) Welding. This paper presents the influence of welding parameters like welding current, welding voltage and gas flow rate on hardness of austenitic stainless steel on 304 grade material during welding. A plan of experiments based on Taguchi technique has been used to acquire the data, An Orthogonal array and signal to noise (S/N) ratio are employed to investigate the welding characteristics of butt joint and optimize the welding parameters. To find out percentage contribution of each input parameter for obtaining optimal conditions, we were used analysis of variance (ANOVA) method. Finally the conformations tests have been carried out to compare the predicted values with the experimental values to confirm its effectiveness in the analysis of hardness
