METHOD OF INSTALLING CONSUMABLE ELECTRODE IN CASTING MOULD Russian patent published in 2013 - IPC C22B9/20 C22B9/21 

FIELD: metallurgy.

SUBSTANCE: proposed method comprises fitting consumable electrode in casting mould, centering it in mould axis and fixing it thereat, welding it to stub end secured at electrode holder, and controlling quality of weld joint between electrode and stub end. Control over quality of said weld joint is performed by measuring intensity of magnetic field induced by short-circuit current in closed coaxial system consisting of internal conductor composed of consumable electrode with stub end welded thereto and external conductor consisting of casting mould and melting chamber jointed therewith in section perpendicular to system axis and crossing weld joint, and comparing measured intensity with reference value to detect defects from the results of comparison.

EFFECT: ruled out emergency in vacuum arc smelting.
