In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW.)In the beginning of D.O.E phase, pilot experiments were performed for preliminary study. The various parameters, their ranges and levels were selected based on results of the pilot study. Suitable Technique for orthogonal arrays was used for design of experiments after the pilot experiments. Based on the findings of the Pilot study, actual experimentation work was designed and input machining parameters and their values finalized. The results are expected to show that the response variables (output parameters) strongly influenced by the control factors (input parameters). So, the results which are obtained after experimentation analyzed and modeled for their application in manufacturing industry. In this work the effect of various parameters on chromium element transfer was studied. L16 Orthogonal array was used & three factors Current, Voltage, Welding Speed were taken. It is concluded that current is the most significant factor for the transfer of chromium element to the weld metal.
