Everywhere in the world researchers are trying to optimize process parameters so that the next time same process parameters are implemented, parameters that are already optimized should be taken into consideration on the first priority level so that the results hence obtained are authentic to an excruciating degree, and a good quality and productivity may be achieved by that particular process. On the contrary what is quite apparent on the ground level is that the stipulated and optimized researched parameters are used in the industry but because of some human errors, environmental conditions, and calibration ambiguity that creep in during the process, the goal of cent percent quality and productivity is not fulfilled. In this study an attempt is made to bridge the gap between the vision of the researchers and the reality on the ground level, and for doing this we need something or someone who keeps a track record of all the included process variables in real time, pre-operation, during the operation, and post operation. The first thing that can be thought of for accomplishing this task is automation, now automation consist of two major parts hardware and software, hardware is something that is used to accomplish a task but the thing that controls the process variables in real time is the software. So software needs to be trained to keep a constant check on the process variables. To train sophisticated software the optimized process variables is a pre requirement. The optimized process parameters can be taken from two sources first is the research studies that have been carried out in past and second is that we can test the process with the required process input variables an then get the optimized values on the first hand, which are hundred percent reliable. In this study tungsten inert gas welding or more popularly known as gas tungsten arc welding is taken in to account and the most effective parameters will be assessed according to the design of experiment provided by the design expert 9 software and experiments will be conducted accordingly, and at the last the optimum values will be noted.
