May 13, 2020 - 8:00am to 5:00pm

This one-day seminar, designed for practicing structural engineers, will provide an overview of what is needed to design reliable welded connections. Based on the requirements of AISC 360 and AWS D1.1, the program will consist of the following six lectures:

  • Welding Processes: an overview of the commonly used welding processes and thermal cutting methods.
  • Principles of Welded Connection Design: twelve principles that should be considered when welded connections are designed.
  • Details of Welded Connections: details associated with welded joints, complete joint penetration groove welds, partial penetration groove welds and fillet welds.
  • Fatigue of Welded Connections: the basis challenges of cyclically loaded connections and the variables that affect the performance of welded connections.
  • Special Welding Applications: specialized applications, including welding on heavy shapes, AESS, HSS, field welding and low temperature applications.
  • Problems and Fixes: solutions for problems of repairs to base metal, out of tolerance joints, mislocated holes, welding on anchor rod, and dealing with welds that were not properly inspected.

The content of the course is generally based on AISC Design Guide 21—A Primer for Engineers, which was written by the presenter.

This course provides 7.5 hours of Continuing Education credit.  CE certificates will be emailed to attendees after the class.
