Design Guide 21, titled "Welded Connections-A Primer for Engineers," is a comprehensive resource providing guidance on various aspects related to structural welding. The guide covers a wide range of topics, including the selection of weld types, weld design, metallurgy, weld repair, weld procedure specifications, quality control, inspection practices, economy considerations, and safety measures.

The second edition of Design Guide 21 incorporates references to relevant provisions in AISC 360-16, AISC 341-16, and AWS D1.1:2015 standards. It introduces new chapters that address seismic considerations and fracture mechanics as applied to welded connections. Furthermore, the guide expands the existing chapter on fatigue and introduces a new chapter on "problems and fixes," which offers practical advice to address commonly encountered problems in welding applications.

Design Guide 21 aims to provide engineers with a comprehensive and up-to-date resource to help them navigate the complexities of structural welding. By covering various factors such as design considerations, material properties, quality control, and safety, the guide equips engineers with the necessary knowledge and tools to ensure robust and reliable welded connections in their designs.
