TWI launches Advanced NDT Appreciation course in the UK

Complex technologies used in industry are changing rapidly, and nowhere is this more true than in the world of non-destructive testing. TWI has recognised industry’s need to keep abreast of these changes and for personnel to gain an understanding of advanced NDT methods. Expertise in this discipline are central to TWI’s portfolio of specialist subjects and has enabled it to design a two week appreciation course covering advanced NDT methods using specialist equipment at its Abington training centre.

The aim of the course is to enable the candidates to explain the basic principles of advanced NDT methods. At the end of the course, they will also be able to identify advantages and disadvantages, both in application and defect detection capabilities of each method, to carry out basic hands-on applications for familiarisation purposes.

The training is aimed at plant engineers, welding and NDT inspectors and practitioners, materials and corrosion engineers, inspection organisations, classification societies and insurance companies.

Dates for the training have now been scheduled over two weeks as follows:

WEEK 1 – click here to find out more

  1. Phased array: An overview of phased array inspection principles, phased array instrument, phased array probes, calibration / checks, inspection sensitivity, principles of data analysis and software familiarity.
  2. TOFD: Introduction into the principles of TOFD inspection, TOFD hardware (pulsars, receivers, motor control, encoders), TOFD data acquisition and interpretation, calibration and optimisation, optimising PCS and angles, flaw location and sizing, limitations of detection and resolution.
  3. Digital Radiography: Principles of digital radiography; calibration of equipment; image processing using phosphor screens; Over view of software specific parameters; calibration of measuring tools; effects of magnification; definition of accuracy constraints and capabilities of CR system; modification of image; use of analysis software.
  4. Thermography: Principles of infrared imaging, calibration of the instrument, storing and retrieving data. Gain an understanding of qualitative thermography in order to identify various patterns. Familiarisation with the conditions required to carry out various inspections including mechanical, electrical components, energy systems and to consider any associated limitations
