FIELD: welding of steels with plated aluminum coating by means of electrode melting in carbon dioxide. ^ SUBSTANCE: flux includes, mass %: zircon concentrate, 7.1 -11.8; nickel, 22.9 - 37.6; fluorspar, 9 - 12,6; cryolite, 41 - 57,4. Such contents of fluorspar and cryolite allow remove aluminum oxide out of welding bath. It provides improved plasticity of welded seam metal at thickness of aluminum coating up to 550 micrometers. ^ EFFECT: enhanced quality of welded seams of steel products. ^ 1 ex
