FIELD: metallurgy.
SUBSTANCE: invention relates to manufacture of consumable electrode for melting ingots of titanium-aluminium alloys containing 15-63 wt % of aluminium. Method comprises preparing a charge by mixing titanium sponge and semi-finished aluminium product, charge portion flow into conical matrix and subsequent through-feed pressing. Titanium sponge is used in the form of spherical bodies with a diameter of 10-25 mm, and aluminium semi-finished product - in the form of bars with the diameter : length ratio = 1:1. Ratio of linear aluminium semi-finished product dimensions to linear titanium sponge dimensions is 2.5-3.5.
EFFECT: increased mechanical properties of electrodes.
