METHODOLOGY for Casting Solutions

Casting Defect Analysis- Protocol

This protocol applies to castings that contain defects

1. Visual Observation of Casting Defect 
• This is best done by actual observation of the casting, but Photos, in some cases may suffice
2. Determination of Casting Features,  including
• Alloy type, actual chemistry is preferable
• Melting type
• Actual pouring temperatures and times
• Pouring method
• In-gate locations, and sizes
• Riser locations, types and sizes
• Locations of chills
• Location and size of chills
• Parting Lines
• Mold and Core Material
3. If Casting is Scrapped
• Remove Section from casting preferably by mechanical methods to avoid affecting microstructure
4. If Casting is to be Salvaged
• Use Portable Microscope to view defect and characterize defect
• If defect is non-metallic, attempt to scrape some particles for observation in the lab
• Drill small holes to analyze chemistry near the defect.
