Abstract
In some embodiments, a method may bond titanium to an intermediate alloy. The method may include layering a portion of an intermediate alloy onto a portion of titanium. The method may include focusing a controlled heat source on a spot of the intermediate alloy to form a weld pool in the intermediate alloy at the spot. The method may include superheating the intermediate alloy in the weld pool above the melting point of the intermediate alloy but below the melting point of titanium such that liquid intermediate alloy contacts the surface of the portion of the titanium heating the portion of the titanium. The method may include diffusing the portions of titanium and intermediate alloy together such that upon the intermediate alloy cooling below the melting point of the intermediate alloy the portions of the intermediate alloy and titanium are bonded forming a weldment.
