Non-Destructive Testing (NDT) is a branch of science and engineering which makes use of non-invasive techniques to determine the integrity of materials, components or structures or endeavours to quantitatively measure some characteristic of an object without rendering it unfit for use after the intervention.

In South Africa the NDT engineering curriculum at Universities is severely neglected. NDT is included in the undergraduate course content of only one university. This knowledge gap leaves the engineering fraternity vulnerable as they are unaware of what their contribution toward successful performance of NDT has to be. It is the aim of this course to make the engineers aware of what NDT is and how NDT should be managed and used as part of the engineering effort in design and operation of a plant.


After completion of the course, delegates should be able to:

  • understand the basic principles of NDT methods and techniques;
  • be aware of technologies and practices of NDT;
  • monitor, improve or control manufacturing processes verify proper processing such as heat treating; and
  • gain exposure to NDT codes and standards.

COURSE DURATION: 3 contact days

Dr. Manfred Johannes got involved in Non-Destructive Testing (NDT) in 1980 at the then Technikon Pretoria, where NDT was included in the curriculum for the National Diploma and National Higher Diploma in Physical Metallurgy. He has been a member of the South African Institute for NDT (SAINT) since 1981 and served as President of SAINT on numerous occasions.

In 1989 he joined Eskom Engineering Investigations (EI) as head of the NDT department. From 1991 he headed up the department for mechanised inspection. This department was developing inspection technologies and equipment for inspection configurations, where manual NDT, especially Ultrasonic Testing (UT), did not provide adequate answers and reliability of the results. This department also planned and executed the first in-service inspection (ISI) on both the nuclear reactor pressure vessels at Koeberg Nuclear Power Station in 1993 and 1994.

Since 2006 Dr Johannes has been employed at the CSIR, where he is involved in establishing capabilities for the inspection of composite materials.
