Cladding is a popular surfacing technique in which a thick material layer covers a relatively low cost structural material to enhance its mechanical properties as well as corrosion resistance properties to increase service life.Among different cladding techniques, an overview on cladding done by Gas Metal Arc Welding (GMAW) is included in this paper.Different special techniques used in GMAW for producing clad parts; their characteristics, microstructure and corrosion resistance properties are discussed.Influence of process parameters on microstructure and corrosion resistance of GMAW clad parts is broadly reviewed.Newer techniques being explored and used regarding GMAW cladding along with the future scope of work are also indicated in this paper.At the end, it can be stated that GMAW is one of the most effective processes for producing clad parts.
