Abstract
AbstractWire and arc additive manufacturing (WAAM) technology is quite impressive and investigated in the last 30 years of development. It fascinates the scientists and manufacturers as it can produce densely deposited metal parts, and the objects produced are almost similar to the desired one. It is a process that includes the deposition of material layer-by-layer. It is gaining importance at a very fast pace as manufacturing industries find it cost- and time-efficient. Here, in this review paper, the mechanism of WAAM techniques, its type, and various components produced by WAAM have been discussed. It also includes the discussion on different surface deposit properties and microstructural properties of the products produced by WAAM. At last, the industrial application and future scope of this technique are also explored.KeywordsAdditive manufacturingWire and arc additive manufacturingMetal additive manufacturing
