This course will focus on the means of achieving the safe design of welded structural connections so that the participant can utilize them and ensure the safety of his design during service life.

Course Outline

After participating in this course, you will be able to:
€¢ Analyze the joints knowing the fundamentals of strength of materials
€¢ Design welded joints having understand basic weld design principles
€¢ Prevent failures with the understanding of basic fundamentals of metal fatigue
€¢ Evaluate and apply the above fundamentals on welded joints and structures


Welding permits the architect and structural engineer the complete freedom of design, freedom of development and the use of modern economical design principles. The widespread recognition of welding as a safe means of making structural connections has come about only after years of diligent efforts, and heavy documentation of research findings and successes. This course will focus on the means of achieving the safe design of welded structural connections so that the participant can utilize them and ensure the safety of his design during service life.


To pass on the knowledge of designing welded structural connections.
To learn how to ensure safety of welded structures against static and fatigue loadings.
To discuss issues about design improvements of welded structural connections

Who should attend

Consulting structural engineers, project managers, construction engineers, fabricators and engineers who would be involved in design and assessment of welded structures, and would like to acquire the basic principles of the weld design. Those engineers who would be involved in the evaluation of the fatigue analysis of structures subjected to repeated loading, will also find the seminar very beneficial.

Faculty: Ashraf Dabayeh, Ph.D.

The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
