Kuldeep Singh (10-MTME-807) Outline : Outline Introduction to NDT Overview of Six Most Common NDT Methods Selected Applications Definition of NDT : The use of noninvasive techniques to determine the integrity of a material, component or structure or quantitatively measure some characteristic of an object. i.e. Inspect or measure without doing harm. Definition of NDT Methods of NDT : Methods of NDT Visual Liquid Penetrant Magnetic Particle Eddy Current Ultrasonic X-ray Microwave Acoustic Emission Thermography Laser Interferometry Replication Flux Leakage Acoustic Microscopy Magnetic Measurements Tap Testing What are Some Uses of NDE Methods? : What are Some Uses of NDE Methods? Flaw Detection and Evaluation Leak Detection Location Determination Dimensional Measurements Structure and Microstructure Characterization Estimation of Mechanical and Physical Properties Stress (Strain) and Dynamic Response Measurements Material Sorting and Chemical Composition Determination Fluorescent penetrant indication When are NDE Methods Used? : When are NDE Methods Used? To assist in product development To screen or sort incoming materials To monitor, improve or control manufacturing processes To verify proper processing such as heat treating To verify proper assembly To inspect for in-service damage There are NDE application at almost any stage in the production or life cycle of a component. Six Most Common NDT Methods : Six Most Common NDT Methods Visual Liquid Penetrant Magnetic Ultrasonic Eddy Current X-ray Visual Inspection : Visual Inspection Liquid Penetrant Inspection : The excess liquid is removed from the surface of the part. Liquid Penetrant Inspection Magnetic Particle Inspection : Magnetic Particle Inspection The part is magnetized. Finely milled iron particles coated with a dye pigment are then applied to the specimen. These particles are attracted to magnetic flux leakage fields and will cluster to form an indication directly over the discontinuity. This indication can be visually detected under proper lighting conditions. Magnetic Particle Crack Indications : Magnetic Particle Crack Indications Radiography : Radiography The radiation used in radiography testing is a higher energy (shorter wavelength) version of the electromagnetic waves that we see as visible light. The radiation can come from an X-ray generator or a radioactive source. Film Radiography : Film Radiography Top view of developed film X-ray film The film darkness (density) will vary with the amount of radiation reaching the film through the test object. Eddy Current Testing : Conductive material Coil Eddy Current Testing Eddy Current Testing : Eddy Current Testing Eddy current testing is particularly well suited for detecting surface cracks but can also be used to make electrical conductivity and coating thickness measurements. Here a small surface probe is scanned over the part surface in an attempt to detect a crack. Ultrasonic Inspection (Pulse-Echo) : High frequency sound waves are introduced into a material and they are reflected back from surfaces or flaws. Reflected sound energy is displayed versus time, and inspector can visualize a cross section of the specimen showing the depth of features that reflect sound. f plate crack initial pulse crack echo back surface echo Oscilloscope, or flaw detector screen Ultrasonic Inspection (Pulse-Echo) Common Application of NDT : Common Application of NDT Inspection of Raw Products Inspection Following Secondary Processing In-Services Damage Inspection Inspection of Raw Products : Inspection of Raw Products Forgings, Castings, Extrusions, etc. Inspection Following Secondary Processing : Machining Welding Grinding Heat treating Plating etc. Inspection Following Secondary Processing Inspection For In-Service Damage : Cracking Corrosion Erosion/Wear Heat Damage etc. Inspection For In-Service Damage Special Measurements : Special Measurements Boeing employees in Philadelphia were given the privilege of evaluating the Liberty Bell for damage using NDT techniques. Eddy current methods were used to measure the electrical conductivity of the Bell's bronze casing at various points to evaluate its uniformity. Conclusions : Conclusions Testing without Destroying parts Cost Effective Effective response Time Highly accurate On site testing Thank you You do not have the permission to view this presentation.
