Seminar on Advances in Welding Technologies

Date: 11 Jul 2013 - 11 Jul 2013

Venue: SIMTech Auditorium, Level 3


Welding is one of the most important joining processes and it plays a predominant role in manufacturing industry. The seminar will focus on the state-of-the-art welding technologies such as welding processes, weldability of various materials and their applications in Aerospace, Oil & Gas, Marine & Offshore, and Precision Engineering industrial sectors. Prominent experts from the US, Europe and Asia will be addressing the advancements in welding technology from international perspectives. The seminar provides an excellent opportunity for scientists and industrial experts to share their knowledge on the latest development and trends in welding technologies for industrial applications. It can also lead to the establishment of a platform for further collaborative research and development. This event is organised by SIMTech, PE COI in collaboration with the Singapore Welding Society (SWS). For more details, please click here


About the Speakers

Professor Zhang YuMing, a Fellow of AWS and ASME, has been with the University of Kentucky, USA since 1991 where he directs research efforts on welding process, sensing and control. He received his BS and MS degrees in control and PhD degree in welding all from Harbin Institute of Technology, China. His research has brought him 145 peer-reviewed journal publications, 6 US patents, and recognitions from The Institution of Mechanical Engineers (United Kingdom), International Federation of Automatic Control (IFAC), and American Welding Society. Three of his PhD students received the Henry Granjon Prize from the International Institute of Welding (IIW).


Dr Herbert Heuser has 23 years head of the Quality Department at Böhler Welding in Hamm (formerly Thyssen Welding and Böhler Thyssen Welding), Germany, which is one of the leading companies for production of welding consumables. He was responsible for research and development, for the application department, the quality assurance and the laboratories. One of his areas of works is the investigation and development of matching filler metals for creep resistant steels. Since 3 1/2 years he is Global Segment Manager for Thermal Power Plants. He holds an MS in mechanical engineering from Technische Hochschule Aachen and a PhD from University of Paderborn. Before he joined Thyssen Welding 26 years ago he worked 8 years at the research center of an institute of the German Welding Society "DVS". 


Ms Teresa Melfi  has worked as an engineer in the welding industry for over 30 years, with extensive global experience in the design, manufacture and application of welding consumables.  She currently holds a management position in Research and Development at Lincoln Electric Headquarters in the USA.  Ms. Melfi is chair of the AWS committee responsible for writing submerged arc welding specifications and is a member of ASME Section IX.  She is Chairman of the International Institute of Welding technical commission covering pressure vessels and pipelines. Ms. Melfi holds numerous patents for welding consumables and welding processes, and her publications are frequently referenced in the industry.


Professor Manabu Tanaka received the B.Eng. degree, the M.Eng. degree in welding, and the Ph.D. degree from Osaka University, Osaka, Japan, in 1990, 1992, and 2000, respectively. In 1992, he became a Research Associate with the Joining and Welding Research Institute, Osaka University. He became an Associate Professor in 2003 and a Professor in 2008 and, since then, he has continued his career at Osaka University. His research interests include the physics of arc welding, including plasma diagnostics, electrode phenomena, and numerical modeling. 


Mr Christopher Scott Punshon  joined TWI in 1983. Early research work addressed quality and properties in electron beam (EB) welds in heavy section steels and in particular examined the factors affecting fatigue performance and fracture toughness of EB welds in alloy and C-Mn steels. As EB Applications section manager he was responsible for developing applications of EB processing including welding, melting, surfacing and heat treatment in a range of material types and industry sectors. More recently he has taken responsibility in developing new business and continuing process development in local vacuum and reduced pressure EB processing predominantly for the power generation (especially nuclear fission and fusion), oil and gas industries and for large science projects. He is now a consultant in the EB section with joint responsibilities for business development and managing large projects.


Mr Kari Ahonen has a strong experience in production technology transfer and development of heavy welding systems as wells as consultative sales of related technologies in different areas of the world. In his work in different global companies he has been combining the local working cultures and quality issues to productivity development based on his automation technology knowledge (Master of Science in Automation Technology from Tampere University of Technology, Finland) and welding (International Welding Engineer from Lappeenranta University of Technology, Finland). The key target in his development and consultation projects has been to keep up the practical approach towards all processes in question including the welding quality systems and welding development.


Dr Bi Guijun  is a research scientist from Joining Technology Group, SIMTech. He received his PhD in laser material processing from Fraunhofer Institute for Laser Technology and RWTH Aachen University, Germany in 2004. He started his career as a research fellow at Rolls-Royce Technology Center in School of Mechanical, Materials and Manufacturing Engineering, University of Nottingham, UK. In 2008, he joined SIMTech. His research concentrates on laser aided additive manufacturing for surface modification, repair and 3D additive manufacturing, as well as the applications in marine, aerospace, oil & gas, PE etc.


Dr Elin Marianne Westin  holds a M.Sc. degree in mechanical engineering from Luleå University of Technology, Sweden and an international welding engineer certificate and a PhD degree in material science from the Royal Institute of Technology (KTH) in Stockholm. She worked 2002-2010 for Outokumpu Stainless being responsible for welding research on duplex stainless steels. Dr. Westin has published 13 peer-reviewed journal papers and 14 conference papers. Since 2011 she is employed at Böhler Schweisstechnik GmbH Austria, where she works as product sales manager focusing on high-alloyed flux-cored wires. Dr. Westin is since 2010 vice chairman in the IIW commission IX-H. Mr Royce Lee  graduated from Nanyang Technological University with a Bachelor degree in Engineering with honours. He is currently an area sales and applications engineer with TRUMPF laser division specialising in laser welding, marking and micromachining.


Dr Wei Jun  joined Singapore Institute of Manufacturing Technology since 1997, and is currently the Group Manager of Joining Technology Group.
