Abstract:
1. A welded component, comprising: a first alloy subcomponent; a second alloy subcomponent; and a weld between the first alloy subcomponent and the second alloy subcomponent; wherein the weld includes a gradient having a transition region, the transition region formed by a plurality of shims; wherein the gradient includes a first welded shim composition at least partially formed by welding of a first shim having a first shim composition, a second welded shim composition at least partially formed by welding of a second shim having a second shim composition, a shim-shim transition composition between the first welded shim composition and the second welded shim composition, a first shim-alloy transition composition between the first welded shim composition and the first alloy subcomponent, and a second shim-alloy transition composition between the second welded shim composition and the second alloy subcomponent; wherein the first shim composition includes a nickel-based alloy including, by weight, up to about 22% chromium; wherein the gradient has a gradient composition, the gradient composition increasing or decreasing in concentration, by weight, of one or both of aluminum and titanium front the first alloy subcomponent, through the first welded shim composition, through the shim-shim transition composition, through the second welded shim composition, to the second alloy subcomponent.
