The discovery by researchers that the physio-chemical properties of a substance can be influenced by size led to a realization of the importance of Nano particles. Due to its excellent characteristics, these materials have been a source of interest for researchers in multidisciplinary fields. The morphological features of nanoparticles always garner prodigious attention because of the influence morphology has over most of the Nanoparticles’ properties. This review provides insight to the morphological characterization and physio-chemical of its properties.
Welding is applied in every industry and it’s a major method of manufacturing and revamping metal products because its generally economical, efficient and reliable as a means of joining together metals. Various ways have been proposed to improve the process ranging from adjusting the various welding parameters like welding current, voltage, arc length, width, type of shielding gas used, to using arc pulsing. The method that has however gained the most attention is the Activated-flux TIG welding process which utilizes welding flux to help reduce the bead width and increase the weld penetration. In order to improve the TIG welding process’s industrial efficiency and penetration ability, one method commonly applied is the use of activating flux with the welding process. This review provides insight to the impact of Activated - Flux Tungsten Inert Gas Welding on weld joint of a materials metal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
