This paper is intended to evaluate the process parameters and decision variables for framing an optimization function to make the welding of Austenitic stainless steel alloy-304L plates more reliable. This is made by finding the decision variables involved in the welding operation. It is always important for the process to be done effectively and efficiently. The present work evaluates various parameters involved in plasma arc welding, then were analyzed critically with respect to their boundary conditions. Then the optimization function is formulated, there after the constraints involved in making the welding process were found and also the conditions were defined. Next optimization of this objective function is done by appropriate methods. Here in this case the objective function involved multiple number of decision variables and also it has got mixed type of constraints. Hence in order to solve such problem Kuhn-tucker method is applied. And at the end the optimal values for the decision variables were found. By adapting these set of values in the welding the process got optimized.
