Integrity NDT Projects Hosts VUT Students for an In-Depth Exploration of Non-Destructive Testing

Further solidifying the collaborative spirit established through the December 2023 Memorandum of Understanding (MOU) between Two Roads Group and the Vaal University of Technology (VUT),Integrity NDT Projects, a member company of Two Roads Group, successfully hosted a delegation of VUT students on Tuesday, May 28, 2024.

This initiative aligns seamlessly with the MOU’s core objective of cultivating future professionals in the critical field of Non-Destructive Testing (NDT). The meticulously designed program provided VUT students with a comprehensive understanding of the essential role NDT plays in safeguarding the integrity and reliability of infrastructure, with a particular focus on South Africa’s power generation sector.

The program embarked on a comprehensive exploration of NDT, encompassing a multitude of topics such as:

  • Fundamentals of NDT and Significance in the Power Industry: This session provided a foundational understanding of NDT principles and its critical role in ensuring the safety and reliability of power generation infrastructure. Students gained valuable insights into how NDT helps prevent catastrophic failures, equipment downtime, and potential safety hazards.
  • Implementation Strategies of NDT at Power Plants: Students gained practical knowledge of how NDT techniques are implemented within the context of power plants. They explored the specific NDT methods used at various stages of a power plant’s lifecycle, from construction and commissioning to in-service inspections and maintenance outages.
  • Examination of NDT Processes and Methodologies: The program delved into the intricacies of various NDT methods employed in real-world scenarios, including:
    • Ultrasonic/Wall Thickness Testing: This method uses high-frequency sound waves to precisely measure the thickness of materials and detect internal flaws that could compromise structural integrity.
    • Positive Material Identification: This technique ensures components are constructed from the correct materials for optimal performance and safety. It can involve various methods such as spark optical emission spectroscopy or X-ray fluorescence analysis.
    • Dye Penetrant Testing: A popular method for revealing surface-breaking cracks and discontinuities on a component’s surface. A colored dye is applied to penetrate these openings, and then a developer is used to draw the dye out, making the cracks visible for inspection.
    • Magnetic Particle Testing: This method is effective in detecting surface and near-surface cracks in ferromagnetic materials like steel. It utilizes a strong magnetic field to magnetize the component, and then finely divided magnetic particles are applied. These particles are attracted to areas of leakage flux, which can indicate the presence of cracks.
    • Phased Array UT: An advanced ultrasonic testing technique offering superior versatility and precision in flaw detection. By electronically controlling the direction and focusing of sound waves, phased array UT can be used to inspect complex geometries and weldments more effectively than conventional ultrasonic testing.
    • Portable Hardness Testing: This method determines the hardness of a material at a specific location. Hardness is an important indicator of a material’s strength and wear resistance.
    • Radiographic Testing: This technique utilizes X-rays or gamma rays to create images that reveal internal defects within a material. Radiographic testing is particularly valuable for inspecting welds and thick components where other NDT methods may have limitations.

Kabelo Molaudzi, Key Accounts Executive at Integrity NDT Projects, stated, “We were delighted to welcome VUT students to our facility and share our knowledge of NDT. This was a valuable opportunity to showcase the practical applications of NDT and ignite a passion for this field in the upcoming generation of NDT professionals. We believe that our collaboration with VUT will be instrumental in developing a highly skilled and qualified NDT workforce in South Africa.”


Underscoring Integrity NDT Projects’ dedication to staying at the forefront of the NDT industry, it’s noteworthy that even while hosting the VUT students, a separate team from the company is currently attending the 20th World Conference on Non-Destructive Testing (20th WCNDT) in Incheon, South Korea. This commitment to continuous learning and staying abreast of the latest advancements in NDT on a global scale ensures that Integrity NDT Projects can provide their clients with the most effective and up-to-date NDT solutions.
