Abstract : This study was conducted in order to examine the effect of the welding current and the gas pressure of argon on the welded joints' characteristics, especially the bending properties. Welding using the Tungsten inert gas (TIG) is conducted on 304-stainless-steel sheets based on the probable values of currents and welding gas pressures. Accordingly, the impact of both parameters on the max bending force (MBF) value of the welded joints by TIG was understood. Using the Design of the experiment (Version.10) denoted by (DOE), the experiment's design matrix was determined based on the input factors values. Also, a mathematical and empirical model was attained based on a technique known as Response-Surface-Methodology (RSM). The proposed model dealt with the effect of the prementioned welding parameters on the welded zone’s MBF value, in which the parameters are the gas pressure and the current values. Finally, verification of the model adequacy was performed using ANOVA, which is the analysis of variance.
