Abstract

PURPOSE:To improve the notch toughness and pinhole resistance of weld metal given by a titled wire by regulating the respective amts. of C, Si and Mn in a metallic sleeve as well as CaF2, Al-Mg alloy, Ni, Mn and O in a flux respectively; CONSTITUTION:In a titled wire wherein 10-30% flux, by weight %, based on the total weight of a wire is packed in a metallic sleeve, the compositions of the metallic sleeve and the flux are regulated as follows: A steel material contg. <=0.055% C, <=0.1% Si, and 0.15-0.50% Mn based on the total weight of the wire, and consisting of the balance Fe and unavoidable impurities is used for the metallic sleeve. The flux is formulated to contain 3.5-5.5% an Al-Mg alloy contg. 8.0-12.5% CaF2 and 30-70% Al, based on the total weight of the wire, 1.5-4.0% Ni in the form of Ni and NiO, 0.3-1.7% Mn in the form of >=1 kind of electrolytic Mn, MnO and MnO2, and 0.10-0.34% O in the form of the above-described NiO, MnO, MnO2 and >=1 kind of FeO, Fe2O3 and Fe3O4.
