Choosing the right NDT specialist is the foundation for ensuring the quality and safety of structures, industrial installations and welded joints. An experienced specialist minimizes the risk of errors, saves time and costs, and ensures compliance with applicable standards.
What is non-destructive testing and why is it important?
Non-destructive testing (NDT) is a set of diagnostic methods that allow the technical condition of objects to be assessed without damaging them. They detect material defects such as cracks, welding inconsistencies or casting defects. NDT is essential in many industries, including the petrochemical, energy, aerospace and construction industries.
The most commonly used NDT methods
- Radio-graphic testing (RT): Uses X-rays or gamma rays to detect internal defects in materials.
- Ultrasonic testing (UT): Uses ultrasonic waves to detect surface and internal defects.
- Magnetic particle testing (MT): Uses a magnetic field and magnetic powder to detect surface defects.
- Penetrant testing (PT): Uses penetrating liquid and developer to detect surface defects.
- Visual Testing (VT): This involves a visual assessment of the technical condition of the object.
- Eddy Current Testing (ET): This uses the phenomenon of electromagnetic induction to detect surface and subsurface defects.
- Leak Testing (LT): This is used to assess the tightness of tanks, pipelines and other structures.

Criteria for choosing an NDT specialists
When choosing an NDT specialist, pay attention to the following criteria:
- Certificates and authorizations: The specialist should have certificates confirming his competence in the applied testing methods, in accordance with ISO 9712. Qualification levels I, II or III are desirable, depending on the scope of testing.
- Experience: Experience in working with a given testing method is crucial to ensure reliable results.
- Knowledge: The specialist should have theoretical and practical knowledge of NDT methods, materials science, and applicable standards and regulations.
- Reporting skills: The specialist should prepare clear and comprehensible test reports containing all the necessary information to make decisions regarding the further use of the facility.
- Access to modern technologies: The use of modern technologies, such as laser scanning and industrial metrology, allows for fast and precise measurements.
The importance of metrology in NDT
Modern industrial metrology plays an increasingly important role in NDT. Precise measurements allow even minor welding inconsistencies, discontinuities in castings and deformations in steel structures to be detected. Laser scanning and 3D metrology enable fast and accurate surface mapping and deformation analysis. This is particularly useful for assessing the technical condition of pipelines, tanks and other structures.

Reporting and documentation
An accurate analysis of NDT test results is the basis for effective diagnostics. A specialist should carry out the tests and provide complete inspection documentation. A professional test report should include:
- A detailed description of the test methods and scope of testing.
- Measurement results with a graphical visualization of non-conformities.
- Recommendations for the further use of the tested object.
Using tools such as PolyWorks Inspector enables precise data analysis and comparison of results with quality standards.
