  • WELDING PROCESS FOR PRODUCING ROTATING TURBOMACHINERY
    Publication number: 20110100961
    Abstract: A method for welding dissimilar metals involved selecting a steel having approximately 1-3 weight % chromium (Cr) content and a first coefficient of thermal expansion at a predetermined first temperature for a first part [14], selecting a nickel-based alloy having a second coefficient of thermal expansion at a second predetermined temperature for a second part [12], the first and second coefficients of thermal expansion having a maximum difference of approximately 2-3% when the first predetermined temperature is approximately 500-550° C. and the second predetermined temperature is approximately 600-650° C., then welding the first part to the second part [12].
