Abstract

In the domain of industrial building and production technology, the welding of dissimilar materials finds a wide range of applications. Unique properties of different materials are utilized to produce addition and cost effectiveness of the product for intended applications. For determining the feasibility of welding of dissimilar metals together to create a strong joint, a number of factors need to be taken into account. This paper discusses critical factors and conditions for welding of dissimilar metals and touches upon the practical challenges arising from different physical and chemical properties of the metals. It presents the latest and pertinent literature dealing with the details about the current fusion and non-fusion processes employed for welding common dissimilar metal combinations. The results suggest that research and development in the field of dissimilar metal welding is still needed, especially in light of the growing need for customized materials in contemporary engineering and industrial applications.
