SUMMARY
The discussion centers on the challenges of inserting stainless steel blades into a nodular iron turbine diaphragm during the casting process. It highlights the risk of blade melting when pouring nodular iron and emphasizes the importance of selecting appropriate manufacturing methods. The recommended methods for diaphragm fabrication include welding, casting, pinning, and machining from a solid plate, with welding being the most reliable and cost-effective option. The discussion also references a tutorial from Texas A&M University that provides further insights into these manufacturing techniques.
