NDT Test Study Guide & Non-Destructive Testing Revision Notes Name: Score: 20 Multiple choice questions Term lof 20 A mechanic has completed a bonded honeycomb repair using the potted repair technique. What NDT method is used to determine the soundness of the repair? radiographic inspection metallic ring test & coin tap test eddy current testing ultrasonic shear wave Term 2 of 20 Match the Dye Penetrant steps to their order CLEAN THE SURFACE PART INSPECT AND INTERPRET RESULTS DWELL TIME REMOVE THE PENETRANT WITH AN EMULSIFIER OR CLEANER APPLY DYE PENETRANT APPLY DEVELOPER aluminum titanium non porous metal copper non porous plastic steel It may be used with steels that have been heat treated for stressed applications THOROUGH PRE-CLEANING OF SURFACE APPLY PENETRANT REMOVE PENETRANT APPLY DEVELOPER INSPECT FOR RESULTS COMPLETELY CLEAN THE PART Term 3 of 20 Types of Ultrasonic inspection include ? pulse echo and resonance wet and dry ultrasonic eddy current visual dye penetrant metallic ring test & coin tap test Term 7 of 20 The testing medium that is generally used in magnetic particle inspection utilizes a ferromagnetic material that has...? high permeability and low retentivity high permeability and high retentivity low permeability and low retentivity high penneability and high retentivity Term 8 of 20 Which of the following materials may not be inspected using the magnetic particle inspection method? 1. Magnesium alloys 2. Aluminum alloys 3. Iron alloys 4. Steel alloys 5. Zinc Alloys TRUE 3, 5, base 125 False Term 9 of 20 There are two methods in magnetizing a part. CHARACTERISTIC OF X-RAY MACHINE FILM CHARACTERISTIC TYPE OF DEFECT TO BE DETECTED EXPOSURE ANGLE INTENSIFYING SCREEN EXPOSURE DISTANCE SIZE AND SHAPE OF OBJECT MATERIAL THICKNESS AND DENSITY THOROUGH PRE-CLEANING OF SURFACE APPLY PENETRANT REMOVE PENETRANT APPLY DEVELOPER INSPECT FOR RESULTS COMPLETELY CLEAN THE PART residual is when the magnetizing force is removed the indicating medium is added. continuous is when the magnetizing force is present the indicating medium is added. continuous magnetization is used when a smaller defect is needed to be detected. CLEAN THE SURFACE PART INSPECT AND INTERPRET RESULTS DWELL TIME REMOVE THE PENETRANT WITH AN EMULSIFIER OR CLEANER APPLY DYE PENETRANT APPLY DEVELOPER Term 10 of 20 A correctly made butt weld will have what bead width [ Select ] to [ Select ] times the thickness of the [ Select ] metal? 2, 4, root 3, 5, base 4, 6, base 1, 2, filler Term 13 of 20 What are the two types of indicating mediums used in magnetic particle inspection? Wet and dry Throwaway and renewable Coarse and fine Gyroscopic and pitot static Term 14 of 20 Liquid or Dye Penetrant is used to detect what type of defect TRANSVERSE CRACKS SURFACE CRACK ULTRASONIC LAMELLAR TEAR Term 15 of 20 Which of the following methods may be suitable to use to detect cracks open to the surface in solid aluminum forgings and castings? Dye penetrant inspection. Magnetic particle inspection. Metallic ring (coin tap) inspection. Eddy current inspection. Ultrasonic inspection. Visual inspection. 1234 2345 2356 1456 Term 16 of 20 In a magnetic particle inspection, a flaw that is perpendicular to the magnetic field flux lines generally causes capillary action flaws on or near the surface a longer than normal penetrating time a large disruption Term 17 of 20 If | have an aluminum part, what NDT methods could | use to find cracks open to the surface? metallic ring test & coin tap test aluminum titanium non porous metal copper non porous plastic steel pulse echo and resonance visual inspection dye penetrant ultrasonic eddy current
