WIRE FOR ELECTROSLAG WELDING, FLUX FOR ELECTROSLAG WELDING AND WELDED JOINT

摘要

The present invention relates to a wire for electroslag welding, which is characterized by containing, in mass% relative to the total mass of the wire, more than 0% but 0.07% or less of C, more than 0% but 0.50% or less of Si, more than 0% but 1.0% or less of Mn, from 6.0% to 15.0% of Ni and 79% or more of Fe, while satisfying formula (1). The present invention also relates to: a flux for electroslag welding, which is used in electroslag welding together with the wire for electroslag welding; and a welded joint which is produced by electroslag welding that uses the wire for electroslag welding and the flux for electroslag welding. 0.150 ≤ C + Si/30 + Mn/20 + Ni/60 ≤ 0.300 (1)
