Course in non-destructive testing for engineers
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 characteristics of an object without rendering it unfit for use after the intervention.
This course was designed to make the engineers aware of what NDT is and how it should be managed and used as part of the engineering effort in the design and operation of a plant.
CPD points: three CPD points from ECSA
Learning outcomes:
After completion of the course, delegates should be able to:
- assist in product development;
- screen or sort incoming materials;
- monitor, improve or control manufacturing processes;
- verify proper processing such as heat treating;
- verify proper assembly; and
- inspect for in-service damage.
Course content:
1. An overview will be given of the 6 most common NDT methods. Emphasis is placed on advantages and disadvantages of these methods and techniques:
Visual Testing (VT) - including remote viewing system
Magnetic Particle Testing (MT) - including flux leakage methods
Penetrant Testing (PT)
Eddy Current Testing (ET) - surface testing as well as tube inspection will be addressed
Ultrasonic Testing (UT) - Including overview of TOFD, PA and mechanised UT
Radiographic Testing (RT) - Including Digital RT
2. Practical demonstrations of the methods will be performed as far as possible, so that the attendees can get a "feel" for what is involved.
3. The origins of defects will be addressed in:
Castings - both as final products (girth gears, shafts and drums as well as the work piece to be used in the forging process
Forgings - Forging processes
Welding - also repair welding on castings
4. NDT is generally performed in line with codes and standards - An overview will be supplied of the most common documents used in South African industries
5. Engineering NDT - What is this?
Who plays what role?
Duties of the design engineer regarding NDT
PSI and ISI
Can NDT do the "job" - three scenarios
6. NDT reports - what must be documented
7. Engineering NDT (continued):
Probability of Detection (POD) - history
DDT, PISC and PANI - why where these studies conducted and what are the conclusions
8. Purchasing NDT:
The Health and Safety Executive (HSE) in the UK issued documents on The Best Practices when Purchasing NDT. These documents and the reason for their philosophy towards
the performance of NDT will be presented and discussed
