Abstract:-Welding technology has been developed to improve welding quality. Especially, plasma arc welding has been used for a wide range of areas. However, welding defects occur because of inappropriate arc conditions and lack of arc control with metal vapor contamination in the arc column and anode root. The metal vapor contamination from the anode is varied by the electrical conductivity of the arc in high-temperature medium. The arc emits intense radiation. In this paper, the temperature distribution of the plasma … Show more
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.
