Vacuum arc remelting is the continuous remelting of a consumable electrode by means of an electric dc arc between the electrode and the base of a copper mold.

Computer Modeling of the Vacuum Arc Remelting (VAR) -- &#; One such approach is vacuum arc remelting (VAR), where a starting electrode, cast from a prior production process, is gradually remelted under vacuum with heat supplied via an electric arc. The bottom of the electrode gradually melts and drips down to a molten pool, which continually solidifies, forming the final ingot.

Vacuum arc remelted (VAR) billets — AlleimaFor applications requiring a high-quality material with low contents of impurities, thus extremely low contents of non-metallic inclusions, steels melted in the normal way can be remelted in a high-vacuum (HV) furnace. This production method is designated VAR (vacuum arc remelting) and 'HV' is added to the steel grade designation.
