Abstract
A method for welding to a superalloy material without causing cracking of the material. The method includes the steps of depositing a weld strip () of a weldable material onto a superalloy substrate material () using a spray deposition process () and then forming a weldment () to the weld strip. None or a controlled amount of the substrate material () is melted during the weld in order to maintain the concentration of strengthening elements in the local melt within a zone of weldability. The spray deposition process may be a thermal process such as HVOF or a cold spray process. A groove () may be formed in a surface () of the superalloy substrate material to receive the weld strip. A diffusion heat treatment step may be used to improve adhesion between the weld strip and the superalloy material.
