Arc Melting - Arc Youkai

Japanese: アーク溶解 - あーくようかい
Arc Melting - Arc Youkai

...This powder metallurgy method was subsequently improved and is still used to produce tungsten and molybdenum. Meanwhile, melting methods have been developed, such as arc melting, which uses the heat from an arc to melt the metal, and electron beam melting, which uses electrons accelerated by high voltage to melt the metal. These methods make it possible to melt fairly large pieces that can still be processed. A copper crucible with a water-cooled exterior is used as the melting container.

*Some of the terminology that refers to "arc melting" is listed below.
