Abstract
A method for joining materials such as metal alloys that includes a first component, wherein the first component includes a first alloy having a known austenization temperature below which martensite forms when the component is heated and then cooled at a predetermined rate of cooling; a second component, wherein the second component includes a second alloy; and a welding apparatus operative to create a weld between the first and second components without crossing the austenization temperature of the first alloy.
