Paper Abstract

A high wear point exists at the notch between adjacent blades forming the outer shroud of a jet engine turbine stage. This notch is commonly hardfaced to reduce wear and improve turbine blade endurance. Until recently, the blades were manually hardfaced by the gas tungsten arc process. A laser hardfacing process was developed for this application which has increased production rates and reduced rework requirements. The laser's precise energy control, inherent repeatability, and ability to be automated are the principal reasons for these process improvements. Laser hardfacing fundamentals and process development are described. Production equipment characteristics are reviewed and unique features of the process are identified. Finally, the results of several years of production hardfacing experience are discussed.
