This report relates to a fusion upset welding method effected using molten slag as resistance-exothermic medium.It is known that most of conventional welding methods effect their welding by means of molten deposit metal formed in a number of ways, but it may also happen that , in the case of welding ordinary and special steels, mechanical properties of deposited metal invariably drop to a considerable extent under all circumstances.On the other hand, the resistance butt welding and flash butt welding methods in which no metal is deposited, necessitate provision of large capacity power source facilities, so that it is difficult to weld a large cross section using normal welding facilities in these welding systems .
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.
