摘要

A weld joint 12 includes low and high alloy steel components 14, 16. A weld bead between the low and high alloy steel components 14, 16 includes a first weld wire 18 in contact with the low alloy steel component 14, a second weld wire 20 in contact with the high alloy steel component 16, and a third weld wire 22 between the first and second weld wires 18, 20. The third weld wire 22 has a higher percentage of chromium than the first weld wire 18 and a lower percentage of chromium than the second weld wire 20. A method for welding includes applying a first weld wire 18 to a low alloy steel component 14, applying a second weld wire 20 to a high alloy steel component 16, and applying a third weld wire 22 between the first and second weld wires 18, 20. The third weld wire 22 has a higher percentage of chromium than the first weld wire 18 and a lower percentage of chromium than the second weld wire 20.
