How are residual stresses caused by welding in metals simulated and used in practical engineering applications?
What are the difficulties and challenges of using FE software to simulate welding?
What are the potential errors and limitations of the FE solutions in predicting residual stresses caused by welding?
This course gives you practical advice with a minimum of theory.
This eLearning course is aimed at engineers and designers who want to become familiar with how the Finite Element method can be used to simulate the welding process in metals and the residual stresses arising from welding.
The course will cover the FE modelling of the welding of metallic structures using filler material where the high temperatures experienced by the materials during welding generate thermo-mechanical stresses and microstructural changes. FE solutions for the post-weld residual stresses will be discussed and compared to experimental measurements.
Difficulties encountered by the FE user and the limitations of FE software in modelling the welding process will be highlighted using examples to demonstrate the mechanics of welding and the expected accuracy of the FE solutions.
The pre-requisite for this course is a working knowledge of linear finite element theory and applications. No prior knowledge of Welding is required. The course is independent of any finite element software code.
The objectives of this course are:
Travel and training budgets are always tight! The e-Learning course has been developed to help you meet your training needs.
If your company has a group of engineers, or specific training requirements across any subjects, please contact us to discuss options.
This is a three-week live web-based eLearning course with a total of 6 hours of tuition (presented as a two-hour session per week). Delegates will be provided with copies of all lecture slides including many self-test problems (with worked solutions).
Self-test questions 1 (optional homework)- Questions to reinforce the topics covered in the lectures
Solutions to self-test questions 1 (Full solutions highlighting the key aspects)
Self-test questions 2 (optional homework)- Questions to reinforce the topics covered in the lectures
Solutions to self-test questions 2

*It is your individual responsibility to check whether these e-learning courses satisfy the criteria set-out by your state engineering board. NAFEMS does not guarantee that your individual board will accept these courses for PDH credit, but we believe that the courses comply with regulations in most US states (except Florida, North Carolina, Louisiana, and New York, where providors are required to be pre-approved)
Telephony surcharges may apply for attendees who are located outside of North America, South America and Europe. These surcharges are related to individuals who join the audio portion of the web-meeting by calling in to the provided toll/toll-free teleconferencing lines. We have made a VoIP option available so anyone attending the class can join using a headset (headphones) connected to the computer. There is no associated surcharge to utilize the VoIP option, and is actually encouraged to ensure NAFEMS is able to keep the e-Learning course fees as low as possible. Please send an email to the e-Learning coordinator (e-learning @ nafems.org ) to determine if these surcharges may apply to your specific case.
Just as with a live face-to-face training course, each registration only covers one person. If you plan to register a large group (10+), please send an email to e-learning @ nafems.org in advance for group discounts.
