Weld repair of steel alloy components

Abstract

A method for repairing a steel alloy article is provided. The method includes depositing, using a first welding process, a first weld repair layer across a surface of the steel alloy article to be repaired. The first weld repair layer forms a heat-affected zone (HAZ) in the steel alloy article beneath the surface. The method also includes tempering the heat-affected zone by depositing, using a second welding process, a second weld repair layer across the first weld repair layer. The first welding technique is different than the second welding process and induces a lower heat input into the steel alloy article than the second welding process, wherein the thickness of the first weld repair layer is thinner than the thickness of the second weld repair layer.
