The systematic approach carried out towards the optimization on the joint of carbon steel and stainless steel SMAW welding. The quality of the welding is depended upon the various parameters which are used in welding. In current work by changing parameters like voltage, polarity and bevel angle, we can easily find the effect on weld joint which is made from carbon steel and stainless steel. The Levels of parameters derived from design of experiment procedure (DOE). The tensile specimen prepared as per the ASTM and tested on the universal testing machine. Response surface methodology has been used to develop the mathematical model for tensile strength. The effect of the different parameter on the tensile strength has been evaluated. The ultrasonic method has been used for finding internal defects like cracks, porosity, etc. The results indicated that electrode diameter current and bevel angle play vital role welding strength. The maximum strength has been achieved by using maximum electrode diameter and current, but bevel angle should be accurate. Very high and very low bevel angle may decreases welding strength.
