2 Interruption in Normal Physical Structure - Keyways, Grooves, Holes present by design Discontinuity Flaw Defect Discontinuity with undesirable connotation - Slag, Porosity, Lamination Flaw which makes component unfit for service - Cracks, Lack of Fusion in Weld
3 Types of Flaws: Planar Flaws (2D) Lack of Fusion, Cracks Volumetric Flaws (3D) Porosity, Inclusions
4 Important Flaw Characteristics in materials Location Surface Flaw Sub-surface Flaw Surface flaw more severe as compared to sub-surface flaw because of higher stress intensity associated with it Code provides guidelines on classification of flaw in to surface or subsurface, if it lies just below the surface of the component
5 Important Flaw Characteristics in materials Shape Flaws with sharp tip like crack more severe than flaws with smooth surface like porosity Small root radius leads to higher stress intensity
6 Important Flaw Characteristics in materials Proximity If two flaws are very close, they influence the stress intensity associated with each other Two flaws shall be separated by the length of the longest flaws, or else they shall be considered together as a singe flaw including the sound region in between
7 Important Flaw Characteristics in materials Nature Weld Flaw - Operator: Porosity, lack of fusion, slag inclusion, undercut - Metallurgical origin: Cold crack, Hot crack, laminar tearing Planar or Volumetric Flaw Planar flaw more severe than volumetric flaw
8 Classification of NDT Methods Non-Destructive Testing Surface Examination Volumetric Examination Performance Test Visual Radiography Acoustic Emission Liquid Penetrant Ultrasonic Testing Leak Test Magnetic Particle Eddy Current
9 NDT Techniques for Welds Conventional X- ray and Gama-ray Radiography Ultrasonic testing Eddy Current testing Magnetic Particle Dye Penatrant Advanced Infra-red Thermography Acoustic Emission Micro-focal radiography Real time radiography Time of Flight Diffraction (UT) Phased array ultrasonic testing X-ray residual stress measurement
10 Dye Penetrant Inspection Surface breaking defects only detected Penetrant applied to the component and drawn into the defects by capillary action Applicable to all non- porous and non absorbing materials. Penetrants are available in many different types Water washable contrast Solvent removable contrast Water washable fluorescent Solvent removable fluorescent Post-emulsifiable fluorescent
11 Dye Penetrant Inspection
12 Dye Penetrant Inspection
13 Dye Penetrant Inspection Step 1. Pre-Cleaning Cleaning preparation is very important on this method. Usually solvent removal is been used
14 Dye Penetrant Inspection Step 2. Apply penetrant After the application of the penetrant the penetrant is normally left on the components surface for approximately 15 minutes (dwell time). The penetrant enters any defects that may be present by capillary action
15 Dye Penetrant Inspection Step 3. Clean off penetrant After sufficient penetration time (dwell time) has been given,excess removal penetrant stage take place. A damped lint free tissue with solvent is used to clean the excess penetrant.
16 Dye Penetrant Inspection Step 3. Apply developer After the excess penetrant is been removed, a thin layer of developer is applied.a penetrant drawn out by reversed capillary action.
17 Dye Penetrant Inspection Step 4. Inspection / development time Inspection should take place immediately after the developer has been applied.any defects present will show as a bleed out during development time.
18 Dye Penetrant Inspection Step 5. Post-Cleaning After the inspection has been performed post cleaning is required to prevent corrosion.
19 Dye Penetrant Inspection Fluorescent Penetrant Bleed out viewed under white light Bleed out viewed under a UV-A light source Colour contrast Penetrant
20 Magnetic Particle Inspection
21 Magnetic Particle Inspection Surface and slight sub-surface detection Relies on magnetization of component being tested Ferro-magnetic materials only can be tested A magnetic field is introduced into a specimen being tested Methods of applying a magnetic field, yolk, permanent magnet, prods and flexible cables. Fine particles of iron powder are applied to the test area Any defect which interrupts the magnetic field, will create a leakage field, which attracts the particles Any defect will show up as either a dark indication or in the case of fluorescent particles under UV-A light a green/yellow indication
22 Magnetic Particle Inspection Electromagnet (yolk) DC or AC Collection of ink particles due to leakage field Prods DC or AC Crack like indicati on Crack like indicati on
23 Magnetic Particle Inspection A crack like indication
24 Magnetic Particle Inspection Alternatively to contrast inks, fluorescent inks may be used for greater sensitivity. These inks require a UV-A light source and a darkened viewing area to inspect the component
25 Magnetic Particle Inspection Typical sequence of operations to inspect a weld Clean area to be tested Apply contrast paint Apply magnetisism to the component Apply ferro-magnetic ink to the component during magnetising Interpret the test area Post clean and de-magnatise if required
26 Magnetic Particle Inspection Advantages Simple to use Inexpensive Rapid results Little surface preparation required More sensitive than visual inspection Disadvantages Surface or slight subsurface detection only Magnetic materials only No indication of defects depths Detection is required in two directions
27 Radiographic Inspection The principles of radiography X or Gamma radiation is imposed upon a test object Radiation is transmitted to varying degrees dependant upon the density of the material through which it is travelling Thinner areas and materials of a less density show as darker areas on the radiograph Thicker areas and materials of a greater density show as lighter areas on a radiograph Applicable to metals,non-metals and composites

42 Radiographic Inspection Advantages Disadvantages Expensive equipment Permanent record Bulky equipment ( x-ray ) Little surface preparation Harmful radiation Defect identification Detection on defect No material type depending on orientation limitation Slow results Required license to operate
43 Basic Principles of Ultrasonic Testing To understand and appreciate the capability and limitation of UT
44 Ultrasonic Inspection Sub-surface detection This detection method uses high frequency sound waves, typically above 2MHz to pass through a material A probe is used which contains a piezo electric crystal to transmit and receive ultrasonic pulses and display the signals on a cathode ray tube or digital display The actual display relates to the time taken for the ultrasonic pulses to travel the distance to the interface and back An interface could be the back of a plate material or a defect For ultrasound to enter a material a couplant must be introduced between the probe and specimen
45 Ultrasonic Inspection Ultrasonic testing is a good technique for the detection of plate laminations and thickness surveys Laminations detected using normal beam probes
46 Ultrasonic Inspection defect echo initial pulse Back wall echo Material Thk defect 0 Compression Probe CRT Display 50
47 Ultrasonic Inspection Pulse echo signals A scan Display Compression probe UT Set, Digital Thickness checking the material
48 Ultrasonic Inspection Ultrasonic testing requires high operator for defect identification Most weld defects detected using angle probes
49 Ultrasonic Inspection UT Set A Scan Display Angle Probe
50 Ultrasonic Inspection initial pulse defect echo Surface distance defect sound path 0 Angle Probe CRT Display 50
51 Ultrasonic Inspection Advantages Disadvantages Trained and skilled Rapid results operator required Sub-surface detection Requires high operator Safe skill Can detect planar defect Good surface finish Capable of measuring the required depth of defects Difficulty on detecting May be battery powered volumetric defect Portable Couplant may contaminate No permanent record
52 Principles and Application of Eddy Current Testing Basic Principle Parameters influencing ECT Equipment for ECT Probe (types, construction and design) Supply, display and measuring unit Reference Standards General Applications Tube testing (Welded and Seamless) Thickness measurement (bare surface and coating) Surface Crack Detection Conductivity measurement (sorting, heat-treatment etc)
53 Illustration material
54 Basic Applications of ECT Crack detection Material thickness measurements Coating thickness measurements Conductivity measurements for: o Material identification o Heat damage detection o Case depth determination o Heat treatment monitoring
55 Advantages Sensitive to small cracks and other defects Detects surface and near surface defects Inspection gives immediate results Equipment is very portable Method can be used for much more than flaw detection Minimum part preparation is required Test probe does not need to contact the part Inspects complex shapes and sizes of conductive materials
56 Limitations Only conductive materials can be inspected Surface must be accessible to the probe Skill and training required is more extensive than other techniques Surface finish and and roughness may interfere Reference standards needed for setup Depth of penetration is limited Flaws such as delaminations that lie parallel to the probe coil winding and probe scan direction are undetectable
57 Parameters Influencing ECT Material Parameters Conductivity Permeability Magnetic Coupling (sensor and test object) Depth of penetration (frequency)
58 Conductivity ( ) Variables affecting : Chemical composition Impurity content Heat-treatment Lattice distortion and lattice defects (Cold work) Hardness Temperature Discontinuities
59 Permeability Material s Flux Density (B) Coil s Mag. Force (H) Non-magnetic Material Material s Flux Density (B) Coil s Mag. Force (H) Magnetic Material Example Cu, SS 304 Steels, Ni-base alloys Low DOP for eddy currents High DOP for eddy currents

Differential Bobbin(ID), Encircling(OD), Surface Flaw detection Reflection Probes Flaw detection and thickness measurement Bobbin(ID) (remote field: driver and sensor) Encircling (OD) Surface Bobbin (ID)
64 Reference Standards Common eddy current reference standards include: Conductivity standards. Flat plate discontinuity standards. Flat plate metal thinning standards (step or tapered wedges). Tube discontinuity standards. Tube metal thinning standards. Hole (with and without fastener) discontinuity standards
65 Basic Applications Crack detection (tubes, components) Material thickness measurements Coating thickness measurements Conductivity measurements for: o Material identification o Heat damage detection o Case depth determination o Heat treatment monitoring
66 Application 1: Tube Testing: Analysis of Signals
67 Tube Testing: Analysis of Signals
68 Tube Testing: Examples Typical flaws which show up, include: Pin-holes Cross cracks lamination Seam cracks Porosity Hook cracks Lack of fusion Edge damage Open seams
69 Application 2:Thickness measurement-principle
70 Thickness measurement-example Thickness of thin metal sheet and foil, and of metallic coatings on metallic and nonmetallic substrate Cross-sectional dimensions of cylindrical tubes and rods Thickness of nonmetallic coatings on metallic substrates
71 Application 3: Coating Thickness Measurement of Thin Conductive Layers It is also possible to measure the thickness of a thin layer of metal on a metallic substrate, provided the two metals have widely differing electrical conductivities. A frequency must be selected such that there is complete eddy current penetration of the layer, but not of the substrate itself. The method has been used successfully for measuring thickness of very thin protective coatings of ferromagnetic metals (i.e. chromium and nickel) on non-ferromagnetic metal bases.
72 Thickness Measurements of Non-conducting Coatings on Conductive Materials o Principle: The thickness of nonmetallic coatings on metal substrates can be determined using effect of liftoff on impedance. The coating serves as a spacer between the probe and the conductive surface. o Applications: thickness measurement of paint and plastic coatings. o Accuracy: Thickness between 0.5 and 25 µm can be measured to an accuracy between -10%/+ 4%.
73 Application 4: Surface Crack Detection Excellent method for detecting surface and near surface defects when the probable defect location and orientation is well known Defects such as cracks are detected when they disrupt the path of eddy currents and weaken their strength Important Considerations A knowledge of probable defect type, position, and orientation. The probe should fit the geometry of the part and the coil must produce eddy currents that will be disrupted by the flaw. Selection of a reasonable probe drive frequency. For surface flaws, use high freq. for maximum resolution and high sensitivity. For subsurface flaws, use lower frequencies to get the required depth of penetration and this results in less sensitivity. For ferromagnetic or highly conductive materials use of an even lower frequency to arrive at some level of penetration. Reference specimens of similar material as component and with features that represent the defect or condition being inspected
