Patent ID: 8119951

Claim:
A method for forming a low alloy steel or a mild steel weld having readily removable slag islands which comprises melting in an electric arc a metal core weld wire to form a low alloy steel or a mild steel weld, the metal core weld wire comprising a steel sheath and a core, the core including a composition disposed therein that includes a slag-modifying additive selected from the group consisting of antimony and compounds thereof, the metal core weld wire containing less than 5% by weight nonmetallic inorganic components and less than 10% by weight chromium wherein forming a low alloy steel weld said wire contains based upon the total weight of the wire about: ELEMENT Wt. % C 0.003-0.13 Mn 0.5-3.5 Si 0.2-2.0 Cr <10 Ni 0.0-3.75 Ti 0.0-0.1 Mo 0.0-1.2 B 0.0-0.1 V 0.0-0.25 Sb 0.04-0.3 Fe 85.6-99.25 and wherein forming a mild steel weld said wire contains based upon the total weight of the wire about: ELEMENT Wt. % C 0.003-0.12 Mn 0.5-3.5 Si 0.2-2.0 Cr 0.0-0.5 Ni 0.0-0.5 Ti 0.0-0.1 Mo 0.0-0.5 B 0.0-0.1 V 0.0-0.5 Sb 0.04-0.3 Fe 96.25-99.25.
