Study Notes
Testing and Inspection in Manufacturing
- Testing involves subjecting products to various conditions to evaluate performance, functionality, and durability.
- Testing aims to replicate real-world usage, identify weaknesses, and pinpoint potential failure points.
- Inspection focuses on scrutinizing components to ensure compliance with specifications and standards.
- Inspection uncovers defects, irregularities, or deviations from standards.
- Early detection allows for corrective measures.
Case Study: Building the A350 Wings in Wales
- Airbus Broughton plant has four separate wing production buildings.
- The A350 production line is as large as Wembley Stadium.
- 550 people assemble A350 wings in 5 days.
- Development used over 4,000 hours of wind tunnel time.
Case Study: Testing New Cars (1)
- A £100 million facility in Warwickshire tests human-driven and autonomous vehicles (electric, combustion, civilian, and military).
- The facility tests advanced driver-assistance systems and connected and autonomous vehicles (lane merging, lane assist, platooning).
- The facility recreates real-world road conditions and allows for testing of driving autonomy.
Case Study: Testing New Cars (2)
- In-door car self-parking without global navigation satellite signals cannot penetrate steel structures.
- Digital twins, simulators, and VR caves reduce the need for physical testing.
- Simulators and test rigs help reduce carbon emissions compared to physical prototyping.

- Dummy positioning tolerance is ±13mm for accurate comparison across vehicles.
- Testing preparation takes 4 days and testing is 200 milliseconds.
- Costs can reach £100,000 per test.
Destructive vs Non-Destructive Testing
- NDT/NDE uses noninvasive techniques to assess materials, components or structures, and quantitatively measure characteristics.
- NDT is used to locate defects in an asset.
- NDE is used to locate defects while simultaneously measuring the size, shape, orientation, and other physical characteristics of the defect.
Common Application of NDT
- Inspection of raw materials: forgings, castings, extrusions, etc.
- Inspection after processing: machining, welding, grinding, heat treatment, plating, etc.
- In-service damage inspection: cracking, corrosion, erosion, wear, heat damage, chemical composition, microstructural dimensions, flaw detection, and leaks.
Industrial Sectors Using NDE
- Energy, Construction, Oil and Gas, and Aerospace use NDE techniques.
Case Study: NDT in the Oil and Gas Industry
- NDT is critical in oil and gas industries to ensure safety and maintain efficiency.
- NDT reduces costs of labor, materials, downtime, and undetected repairs.
- NDT enables objective quality measurements and compliance.
- NDT helps identify defects, such as weld quality, cracks, and corrosion.
Typical NDT Methods
- Visual, Hardness, Micro-hardness, Magnetic Particle, Liquid Penetrant, Ultrasonic, Radiography, and Eddy Current Testing are shown as methods.
Comparison of NDT Methods
- A table displays a side-by-side comparison of different NDT techniques based on factors like industry applications, effect, type of materials, cost, availability of results, Geometry, type of defects, operator skill, and ability to automate.

- 3D scanning allows for faster and more accurate data acquisition compared to previous methods.
Visual Inspection (2)
- Pipeline inspection utilizing drones and thermal imaging cameras identifies heat loss, leaks, and structural issues.
- Thermography uses infrared radiation to create images of an object.
Visual Inspection (3)
- A robot inspects predefined locations for cracks using a thermographic sensor to quickly scan structures.
- The method involves electronic impulse stimulation, followed by infrared camera images generating temperature profile to detect cracks.
- Using drones for data acquisition reduces inspection time substantially
Liquid Penetrant Inspection
- Liquid with high surface wetting characteristics is applied to identify surface breaking defects.
- Excess liquid is removed then a developer is applied to pull the trapped penetrant out the defect,
- Fluorescent dye and UV light is used to increase sensitivity
- This process is used to identify discontinuities within the part.
Magnetic Particle Inspection
- Applying a magnetic field causes ferromagnetic particles to visibly gather around discontinuities/defects.
- The defects appear as small N-S poles due to flux leakages from the magnetic field.
- Method is used to pinpoint and analyze surface level defects
Radiography
- X-ray inspection detects internal flaws such as cracks and porosities.
- Metal denser than a defect shows up brighter in the x-ray image.
Eddy Current Testing
- Eddy current testing detects surface cracks and can measure electrical conductivity and coating thickness.
- The method relies on electromagnetic induction to detect flaws.
Ultrasonic Inspection (Pulse-Echo)
- High-frequency sound waves detect flaws and imperfections through reflection.
- The reflected sound energy displays on the machine, and the amplitude and distance of the reflection depict flaw characteristics.
Case Study: Ultrasonic Armour Inspection
- British military inspects 5 million armour units annually using X-rays.
- Handheld devices apply energy similar to a miniature earthquake to detect issues and flaws.
- The system analyzes results with flexible circuits to provide a pass/fail result.
Aircraft Inspection
- NDT is used extensively during aircraft manufacturing to detect cracks and corrosion damage.
- NDT helps perform flaw inspection during operation based on the identified defects.
Jet Engine Inspection
- Aircraft engines are overhauled after a period of service.
- The process involves disassembly, cleaning, and comprehensive inspection.
- Fluorescent penetrant inspections are employed to check for cracking.
Rail Inspection
- Special cars inspect thousands of miles of rail to detect cracks that could cause derailment.
- Ultrasound inspection methods are applied in railway industries to analyze flaws.
Wire Rope Inspection
- Electromagnetic devices and visual inspections are used to detect damage and broken wires in lifting devices.
- Method detects defects in wire ropes used in installations such as crane liftings.
Bridge Inspection
- Corrosion, cracking, and damage negatively affect bridge performance.
- Visual inspections are conducted every two years.
- Some bridges are fitted with acoustic emission sensors to listen for cracks.
Pipeline Inspection
- NDT is used to inspect pipelines to prevent leaks and environmental damage.
- Testing includes visual inspection, radiography, and electromagnetic testing.
Power Plant Inspection
- Power plants are regularly shut down to inspect for corrosion damage to heat exchanger tubes.
- Eddy current probes are used to pinpoint and detect issues.
Storage Tank Inspection
- Robots use ultrasound to inspect the walls of large above-ground and underground storage tanks for thinning due to corrosion.
- Cameras on articulating arms are employed to inspect internal structural condition and corrosion issues.
Pressure Vessel Inspection
- Pressure vessel failure can lead to large energy releases.
