Weld Cladding, ATIG Welding and Wire Arc Additive Manufacturing: Some Emerging Areas of Welding Research

Abstract

In this article, first, an outline on cladding processes, weld cladding and the use of a buttering layer to improve cladding performance is made. Next, the use of activating flux for having high productivity in GTAW or TIG Welding is highlighted. Lastly, a relatively new area of wire arc additive manufacturing and its opportunities are briefed. This article, in fine, makes an attempt to open up some of the immense possibilities of research in welding.
