Structural Welding: Design and Specification

a seminar on the design and specification of welding for steel-framed structures using the AWS D1.1-2006 Structural Welding Code - Steel, the new AISC 2005 Specification for Structural Steel Buildings, and recent research

This seminar will familiarize you with the AWS D1.1-2006 and the AISC's Steel Building and Seismic specifications. It will also include previews into pending changes in the above specifications, and reveal related areas of research and developments in structural welding.

Improve your design skills.

Learn what conditions create potential failures and how to avoid them through good design and specifications.

Receive tips on proper welding design to reduce cost and avoid problems in fabrication, erection and inspection.

Improve the quality and clarity of your project specifications, as well as update them to the latest standards.

Better understand the engineer's role in specifying inspection and testing requirements, and in making evaluations.

Expand your knowledge of welding symbols to accurately convey your design information.
