IIW Welding Ecourse on Welding Stresses and Distortions from Welding Innovations Network

 

IIW ECourse on Welding Residual Stresses and Distortions from Welding Innovations Network

With the advent of greater demand for online training, HERA, IIW India, SAIW and the CWB Association are cooperating and collaborating to transfer the knowledge and experience of world experts into as many countries on a global basis.

The four organizations have arranged for eCourses to be presented by such world experts to meet the challenges of different time zones, the need to assist individuals and industries to optimize their training times as well as improve their national welding capabilities.

You can make inquiries and bookings with each organization offering the course most suitable for your needs. Links for registration are given later in this brochure.

This is the second eCourse to be offered in a series of three by world expert, Professor Pingsha Dong, University of Michigan, USA. The understanding and techniques offered by this course can lead to significant savings in mitigating the detrimental effects of residual stresses and distortions in practice.

Residual Stresses and Distortions:
Mechanisms, Impact on Structural Integrity, and Mitigation Techniques

PRESENTER: PROFESSOR PINGSHA DONG
University of Michigan, Ann Arbor, Michigan, USA

This eCourse will present how residual stresses and distortions are developed during fusion and solid state welding, and related manufacturing processes, including metal 3D printing and additive manufacturing (AM). Simple analytical models will first be used to describe the underlying mechanisms, and computational modeling results will then be used to demonstrate the relevance of these analytical results for deriving effective solutions to various residual stress and distortion problems experienced by various industry sectors, including aerospace, automotive, heavy equipment, and shipbuilding.

Then, the principles for residual stress and distortion mitigation techniques will be discussed and illustrated with various real-world applications. In addition, how residual stresses and distortions affect components’ structural performance (e.g., fatigue capacity) will be discussed, including how to effectively treat their effects in structural integrity evaluation, based on the most recent research findings.

ABOUT THE SPEAKER

Prof. Pingsha Dong of University of Michigan, is the inventor of the mesh-insensitive structural stress method (also referred to as the Master S-N Curve Method) adopted by the 2007 ASME Div 2 and API 579/ASME FFS-1 Codes and Standards mandated by over 50 countries worldwide. Over the past 10 years, Prof. Dong  has taught courses in fatigue design, fracture control, residual stress/distortion control in over a dozen countries around the globe. 

Prof. Dong has published more than 260 peer reviewed papers in archive journals and major conference proceedings, including over 20 plenary/keynote lectures at major international conferences. 

He has received numerous prestigious national and international awards/recognitions, including AWS Comfort Adams Lecture Award (2019), SNAME Helmer L. Hann Awards (both in 2012 and 2007), IIW Evgeny Paton Prize (2008), R&D Magazine’s R&D 100 Award (2006), TIME Magazine’s Math Innovator (2005), Aviation Week and Space Technology’s Aerospace Laurels Award (2004), SAE Henry Ford Award (2003), AWS R.D. Thomas Award, and ASME G.E.O Widera Literature Award (2002), among many others. 

In addition, he is also a Fellow of ASME, AWS, and IIW.

Who Should Attend?

Designers, structural engineers, consultant engineers, NDT testing lab engineers, mechanical engineers, welding and production engineers, maintenance and quality control engineers, as well as researchers. Delegates are encouraged to bring along their design problems to contribute to discussions and local case studies.

What Industry Areas The eCourse Is Relevant For?

The eCourse will be especially relevant to all professionals in automotive, aerospace, steel construction, steel bridge design, power generation, naval and shipbuilding, offshore construction, pipeline and other industries that apply welding.
