1. What are the methods of film viewing? 2. What is the sensitivity needed in a radiographic film? 3. How it is calculations? 4. For 10mm thickness weld, which is the pentameter using in ASTM & in DIN? 5. What is the acceptable limit of film density as per code? 6. What is the allowable density variation in a RT film? 7. What are the causes for larger densities in RT film? 8. Which are the defects we can get in RT film? 9. How tungsten inclusion be identified in RT films? 10. How will you distinguish film mark and indications? What is the action taken in case of film mark in interpretation? 11. How can we differentiate cracks and lack of side wall fusion? 12. How can we differentiate cracks and under cuts in RT films? 13. Is there a porosity indicator; is it possible to locate its position in weld geometry? 14. Is there any chance for missing slag inclusions in multiple bead welds? If yes, what is the cause for it? 15. What is the definition for spherical and elongated indications? 16. How can we differentiate root shadow and crack? 17. What are the essential identifications required on a film? 18. What are the benefits of using hole penerameter? 19. Where will you put pentameter for SWSI? 20. How you will differentiate whether the pentameter is put on source or film side?
21. What is the technique used to detect back scatter radiation in films? 22. How it will appears in RT films? 23. In a certain job you are not getting required sensitivity, what are the actions you take to get the required sensitivity? 24. What are the essential thinks to be mentioned in RT reports? 25. Mostly at the edge of film we can see elongated indications than we take the same at the center source. What is the cause for that? 26. What is density in RT films? 27. Which are the devices used to check film density? 28. What is the principle of putting pentameters on RT films? 29. How can differentiate X-ray and gamma ray films? 30. For small thickness welds which is preferred X-rays or gamma rays?
