We are pleased to announce the appointment of Dr Channa Nageswaran to the role of Technology Fellow for Advanced Ultrasonic Inspection, recognising over two decades of outstanding contributions to ultrasonic testing (UT) innovation and technical leadership.
Channa joined TWI in 2003 as an Engineering Doctorate student, researching inspection techniques for austenitic welds. Since then, he has become a globally recognised authority in advanced UT techniques. His work has shaped international standards and continues to influence both academic and industrial practice. Channa was subsequently elected Chairman of the Sub-commission for Ultrasonic Testing (UT) of the International Institute of Welding (IIW) and is currently leading the revision of the IIW Handbook on UT of austenitic welds.
Channa is a Fellow of the Institution of Mechanical Engineers, recognised for his contribution in authoring the Health and Safety Executive (HSE) publication on the safety of UK assets at risk of damage by high temperature hydrogen attack (HTHA).
His technical expertise spans the development of austenitic cladding and weld inspection techniques, the detection of HTHA, high temperature ultrasonic testing and the application of full matrix capture (FMC) to identify stress corrosion cracking. Channa has supported the TWI Core Research Programme (CRP) as a Programme Manager and continues to advance research as a Level 3 in phased array ultrasonic testing (PAUT).
We would like to congratulate Channa on his appointment to Technology Fellow, as he joins other leading authorities in their technical fields who have made a significant impact through their technical excellence, expertise and knowledge transfer.
