3 3 Introduction and Background Information 1. Internationally the requirement for process qualification and certification for welding, LBM, AM and NDT is becoming a standard 2. The question for which industry requires an answer is: Can the technologies and Thank processes you utilised provide the results and answers required? 3. The reason for this question is the outsourcing of non-core activities and services and in many instances the experience of non-delivery by unscrupulous technology and service providers 4. Studies such as for instance the PISC exercise, the DDT and PANI have revealed for NDT that one needs to do much more to obtain the desired results 5. Qualification and certification of quality related processes such as laser welding, LBM / AM and NDT demand a major engineering input, to design and develop adequate certifiable processes.

4 4 Purpose of the JNTC 1. Main purposes: Establishing a JNTC within the CSIR as a vehicle for South African industry at large to assure localisation of laser welding and NDT technologies and to facilitate human capital development 2. The initiative was identified in planning and establishing a CSIR flagship programme in 2013 whereby capabilities for the project were found to be wanting and hence had to be developed for the programme. 3. Collaboration between various CSIR BU s (NLC, MSM, DPSS) and the industries involved (e.g. Eskom, Transnet, Denel, the SAAF to mention a few) will enhance capability building in Material Science, Welding technologies (metallic, non-metallic, composites) and NDT 4. The aim is to provide advanced theory training, design capabilities through modelling and simulation and equipment for the qualification and certification of processes as required by the local industries.

5 Scope of activities 1. The scope of the JNTC is to establish itself as a one stop multidisciplinary joining technology & NDT research and development centre for the South African industry. 2. Current and future research projects within the Centre should be of national interest, be industry related and/or driven, be multi-disciplinary in nature whilst striving to promote a research culture among staff (and research students alike) through providing and creating research capacity. 5

6 Scope of activities The activities within the JNTC will strongly overlap with the following areas: Mechanical testing (destructive), Non-destructive evaluation (NDT), Development of Composite materials (specialised cladding compositions), Failure analysis, Manufacturing Management systems, Mechatronics and Robotics, Digital modelling techniques and Reliability testing. 6

8 8 JNTC interactions & supported technologies

9 9 NDT activities internationally in the field of LBM / AM Work performed on European Union projects such as Cordis and Intrapid is very much of interest: Cordis Development into application of x-ray technologies including µ -CT for AM Intrapid - dealing mainly with in-line NDT and Quality Control (QC) technologies Eddy Current Testing Laser Ultrasonic Testing Infrared Thermographic Testing TWI performed the project management for both these efforts The results are available for migration to South Africa Need however funding to do this work in progress

10 9 NDT activities internationally in the field of LBM / AM Development work In-situ Ultrasonic Testing for MTU turbine blades Fraunhofer Institute ITWN Kaiserslauten 1 Work in progress

11 10 NDT activities internationally in the field of LBM Optical in-situ measurements University Erlangen-Nürnberg 2 Work in progress

16 15 NDT activities in South Africa in the field of LBM

17 16 NDT activities in South Africa in the field of LBM µ - Computed Tomography University of Stellenbosch, Wits & NECSA

18 17 Conclutions 1. Even though suitable NDT technologies are available in South Africa it is still required to perform inspection development, inspection qualification and possible certification in parallel to process development 2. Succession planning and the appointment of researchers, both local personnel (students, post-docs and interns) must be funded 3. Appointment of a champion from overseas who can direct the technical content and direction in the NDT development and research process is pursued 4. Localisation and migration of the NDT technologies being developed overseas is a must 5. Many people available to be trained and educated in NDT 6. The USA roadmap emphasizes the importance of NDT

20 19 Conclusions - continued 7. Need to define what in-situ requirements for NDT are 8. Purchase existing technology where available (and reliable) much faster 9. Market the JNTC capabilities to industry Interesting reading: documents documents store 1. The 2015 ICNDT Guide on Research and Development in NDT Nondestructive testing: why it is important and why more research and development should be supported (Dr Tony Dunhill Rolls Royce) 2. A landscape for the future of NDT in the UK economy for your time Any questions???
