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. The method also includes the steps of validating the characteristics of the weld created between the first and second components in real-time during the welding process; modifying the welding apparatus to prepare the surface of the first component prior to welding to assure proper alignment of the first and second components; and/or physically modifying the second component to enhance the welding characteristics and durability thereof.
