A Review on Optimization of Welding Process

In order to meet the global competition and the survival of products in the market a new way of thinking is necessary to change and improve the existing technology and to develop products at economical price. It means not only to invest in procuring new equipments but also effectively control the process variables involved in any manufacturing process. These process variables must be measured, controlled and optimized to get the desired and valuable outputs. The typical process parameters for a welding process which affect the desired output for a welding process are welding speed, arc voltage, welding current etc. The weld process parameters vary for the different type of the welding process chosen. Optimization of the welding process parameters depends upon the ability to measure and control the process variables involved in the welding process. The scope of the paper is to review the state of art of optimization techniques to be used for welding.
