Abstract
Abstract A method of making weld metal having a yield strength in the range of from about 110,000 p.s.i. to about 150,000 p.s.i. and high toughness comprising the step of consuming in a shielded arc a weld wire consisting essentially of, by weight, about 0.12 percent maximum carbon, 0.010 percent maximum phosphorus, 0.010 percent maximum sulfur, 1.2 percent to 2.00 percent manganese, 0.40 percent to 1.00 silicon, 1.5 percent to 3.0 percent nickel, 0.40 percent to 1.00 percent molybdenum, 0.40 percent to 1.00 percent copper, 0.08 percent maximum zirconium, the remainder being essentially iron.

Claim 5
Independent Claim
133 words
A method for making a weldment having a yield strength in the range of from about 110,000 p.s.i. to about 150,000 p.s.i. and high toughness comprising the steps forming a joint between members of steel of the class HY-110 to HY-150 of; depositing a weld wire in a joint to form a weldment therein by consuming the weld wire in a shielded arc at said joint, the weld wire consisting essentially of, by weight, about 0.12 percent maximum carbon, 0.010 percent maximum phosphorus, 0.101 percent maximum sulfur, 1.2 percent to 2.00 percent manganese, 0.040 percent to 1.00 percent silicon, 1.5 percent to 3.0 percent nickel, 0.40 percent to 1.00 percent molybdenum, 1.00 percent maximum copper, 0.08 percent maximum zirconium, 1.00 percent maximum tungsten, 0.08 percent maximum titanium, and the remainder being essentially iron.
Claim 6
Dependent Claim
27 words
A method according to claim 6 wherein the weld wire contains, by weight, about 0.08 percent carbon, 0.81 percent silicon, 0.60 percent copper and 0.64 percent molybdenum.
