Professors Ganna Stovpchenko and Lev Medovar of the E. O. Paton Welding Institute and Elmet-Roll, Ukraine, describe the electro-slag remelting process. This is an important process for special steels and other metals used in critical applications. It uses an alloy as a consumable electrode to create a new ingot via a special slag. The consumable droplets travel through the slag to the bottom of a mold, with the slag having the function of cleaning the molten metal.
