  1. Development of Electron Beam welding for similar and dissimilar joints of 9Cr-1Mo Steel and Stainless Steel 316L(N) CVS Murthy1 P Mastanaiah1 Shaju K Albert2 Chitta Ranjan Das2Dasarath Ram1AK Bhaduri2 1 Defence Research and Development Laboratory, Hyderabad 2 Indira Gandhi Center for Atomic Research, Kalpakkam

  2. Collaborative Project - IGCAR & DRDL • EB Welding of SS316 LN to SS316L(N) • EB Welding of 9Cr-1Mo Steel to 9Cr-1Mo Steel • EB Welding of 9Cr-1Mo Steel to SS316L(N) • EB Welding of LAFM Steel to SS316L(N)

  3. EXPERIMENTATION 9Cr-1Mo Steel to SS316L(N) SS316L(N) to SS316L(N) 9Cr-1Mo Steel to 9Cr-1Mo Steel EBW • Tensile Test • Charpy V-notch Impact Test • Bend (face/root) Test • Microhardness

  4. EB Welding Parameters 9Cr-1Mo Steel to 9Cr-1Mo Steel SS316L(N) to SS316L(N) 9Cr-1Mo Steel to SS316L(N)

  5. TENSILE PROPERTIES

  6. MICROHARDNESS

  7. Charpy V-notch Impact Test Temperature : 21.50C

  8. Bend Test EB Welds of SS316LN and 9Cr-1Mo Steel • Three point bend test • Specimen prepared as per • ASME B&PVC Code Section IX

  9. Bend Test Crack Crack Bend specimens - Dissimilar EB Weld

  10. Macrostructure of weld of 9Cr-1Mo Steel

  11. Macrostructures of Dissimilar Weld • Lack of sidewall fusion / crack observed at the SS316 weld interface

  12. Macro/Micro structures of SS316L(N) EB Welds SS EB weld Macrostructure of EB Weld of SS316L(N)

  13. THANK YOU
