Non-destructive inspection is used by manufacturers to inspect and evaluate the properties of materials without inflicting damage on the component or system part(s). Non-destructive inspection is used in the aerospace and automotive industries. Non-destructive inspection is important for accident prevention, to improve product reliability, and to determine acceptance to a given requirement.
Benefits of non-destructive inspection
Non-destructive inspection can be scheduled at each stage of the manufacturing process. If a product does not pass inspection, it can be rejected and returned for repairs. If design requirements or projected life span are not met – e.g. due to manufacturing defects, repair or early replacement – time and labor costs can become expensive. Non-destructive inspection is designed to cut these unnecessary costs.
Mechanical integrity refers to the inspection of crucial process equipment to ensure it is designed and installed properly, and that it operates and is maintained effectively. Ensuring mechanical integrity can be done in a number of different ways.
Steps of a non-destructive inspection
Within non-destructive inspection, robotics are employed to meet even the most large scale inspection needs. A robotic non-destructive inspection should fulfill the needs of a manufacturer, whether it be balancing multiple complex part geometries, meeting tight space constraints, or the need for high accuracy and repeatability. In addition to robotics, a proper non-destructive inspection will include the integration of customer-specified acquisition software. The software would be able to program the adequate inspection cycle based on the company’s needs.
The following procedures are involved in non-destructive inspection:
Ultrasonic inspection: this form of inspection uses short, high-frequency ultrasonic waves to pinpoint flaws in a material. Ultrasonic inspections are useful because they can detect flaws on or underneath the surface.
X-ray: this form of inspection enables you to detect flaws at smaller sizes. Whether traditional or sophisticated, x-ray techniques continue to be an important part of the non-destructive inspection process.
Shearography: laser shearography is used when an inspection needs to be conducted in an expedited manner. It allows users to quickly measure small-to-large geometries, yielding real-time results.
Eddy current: this form of testing uses electromagnetic waves and is generally used for surface and tubing inspections. The induction is used to detect and characterize surface flaws in conductive materials.
