Proceedings from the 1997 Joining and Repair of Gas Turbine Components Conference. Proper joining techniques and procedures are important factors that can influence component design life expectancy. Many components are welded and brazed before being installed, and service related problems often require repair procedures. These proceedings address many aspects of joining and the repair of gas turbine components. Included is practical information on handling different families of alloys, various welding procedures, brazing procedures, process modeling, defect mechanisms and their elimination, and the effects of chemical composition and microstructure on weldability and repairability.
