7F Gas Turbine Nozzle Repair: Proven LPM® technology for cycling units
Liburdi’s LPM® technology has been proven to save operators money by extending component lives. As a high-strength metal replacement process it was developed for the repair of gas turbine components over 30 years ago. Since that time it has proven itself a useful and cost effective process applicable to both repairs and new-component manufacture on polycrystal, DS and single crystal superalloys.
As utility owners find their operating profiles shifting into starts-based maintenance cycles, the component life-limiting damage mechanisms have also shifted from creep and coating consumption to thermal-fatigue cracking. Such cracking is not well addressed by braze repairs, is tedious to rectify weld repairs, and is very expensive to patch by couponing.
LPM® technology offers a unique way to repair damage which is sufficiently ductile and has low distortion. This webinar with explain the process and materials, how and why the preparation is key to the process, and show practical results from prior repairs. And yes, Liburdi can both re-repair LPM® and weld upon LPM®. After the webinar, there will be a chance to ask questions about your applications.
