Weld wire with enhanced slag removal

A metal core weld wire for producing weld deposits with improved removability of slag islands comprising a steel sheath and a core, a core composition disposed in the core, the core composition including 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 wherein the wire contains in percent by weight approximately:

• ELEMENT AMOUNT 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

The wire of claim 17 wherein the core composition contains in percent by weight based upon the total weight of the wire approximately:

• ELEMENT AMOUNT 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 0.0-44.0

A metal core weld wire for producing weld deposits with improved removability of slag islands comprising a steel sheath and a core, a core composition disposed in the core, the core composition including at least 0.03% by weight of 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 wherein the wire contains at least about 0.5% manganese by weight, at least about 0.2% by weight silicon, about 0.03 to 0.05% by weight titanium, and about 0.002 to 0.004% by weight boron based on the total weight of the wire.
