    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.
