NDT of Additively-Manufactured Components

Webinars 15 December 2022

NDT and Condition Monitoring Technical Group Meeting:
NDT of Additively-Manufactured Components

This webinar is aimed at professionals who are responsible for the specification, manufacturing and quality control of additively-manufactured components.

The aims of the webinar are:

  • To identify the factors influencing quality in AM components from a process perspective;
  • To understand the characteristics of potential imperfections in AM components and their influence on the ability of inspection/NDT methods to detect them;
  • To examine the performance of different NDT methods for detection of imperfections;
  • To provide a framework for setting of appropriate specifications for the testing and acceptance of AM components.

Experts from industry and TWI Ltd will be presenting on a range of topics:

  • Yasser Aboura, Materials Engineer, TWI Ltd on Ti64 AM case study: Cracking in a TI64 WAAM trial 

  • Graham Edwards, Consultant, TWI Ltd on NDE of Additively-Manufactured Components

  • Prof Charles MacLeod, Babcock International Group/RAEng Chair in Sensor-Driven Automated High-Integrity Welding on The Challenges in Developing NDT Methods for Additive Manufacture: TWI’s Experience.

Prof Charles N MacLeod

Professor of Electronic And Electrical Engineering Advanced Manufacturing and Materials
Strathclyde University

Charles has over 15 years' experience in Advanced Automated PAUT NDE and leads Strathclyde Automated In-Process NDE activities during welding and additive manufacturing.

His presentation will cover state-of-the-art in-process ultrasonic and electromagnetic testing during Wire+Arc Additive Manufacturing.

Graham Edwards - Consultant, Non-Destructive Testing Group

Graham Edwards

Consultant, Non-Destructive Testing Group

Graham Edwards has over 45 years of experience in Non-Destructive Testing (NDT). Along with several other graduates, he started his career in NDT with the Unit Inspection Company, where he received training in all aspects of NDT and weld inspection. In 1973, he was one of the first ultrasonic test technicians to gain CSWIP approval. For the next four years, he worked in the North Sea offshore oil, the French nuclear power and Middle Eastern petrochemical industries. In 1977 he joined Baugh and Weedon Ltd as an applications engineer, and was involved in the development of the award winning ‘Seaprobe’ underwater ultrasonic test equipment. In 1981 he became a lecturer in the School of Applied NDT at The Welding Institute (TWI), before moving over to the NDT Research department in 1986. There, his research projects included NDT of plastics and composites, expert systems, and acceptance criteria in BS5500 for ultrasonic testing. He also set up the specialist site services team. While at TWI, he collaborated with the French Welding Institute on the NDT of fillet welds and was seconded to the Edison Welding Institute in the USA for two years to set up the NDT section there. In 1997 he moved to Plant Integrity (PI) Ltd, a subsidiary of TWI, as a plant assessment engineer, and ran many of the early inspections using the Teletest Long Range Ultrasonic Test (LRUT) system.

After 7 years as an independent consultant in NDT, he moved back to TWI in 2005 and has since managed many collaborative projects in topics ranging from guided wave inspection of aircraft wiring to robotic inspection of mooring chains. He is currently in the Monitoring and Inspection Research section (CSM) at TWI, where he is developing continuous monitoring techniques for quality control during manufacture and structural health in service.

Dr Yasser Aboura - Materials Engineer Project Leader

Dr Yasser Aboura

Materials Engineer Project Leader

Yasser has dedicated the last 10 years studying and working in the field of material science. He graduated  with a PHD from the university of Manchester in 2019. With TWI Yasser works as a materials engineer project leader where he invest his time in unlocking failure investigations and assessing weld qualifications projects for the energy and defence sectors. Most recently, Yasser has been taking part in a collaborative research project carrying out material development and characterisation for next generation aluminium based hydrogen fuel storage tanks based on WAAM technology. A thorough materials failure investigation is a key element of the overall root cause analysis following the failure of an industrial component and working with TWI is allowing Yasser to experiment with and find best practices in employing failure mechanisms for a number of projects related to additive manufactured aluminium and titanium based alloys for the transport and defence sector.
