The American Welding Society (AWS) released the hard copy of the 2020 edition of the D1.1 structural welding code. To improve clarity and understanding of the code provisions, the update includes important changes in the text and commentary. The code covers the welding requirements for any type of welded structure made from commonly used carbon and low-alloy constructional steels. Clauses 1 through 11 constitute a body of rules for the regulation of welding in steel construction. There are eight normative and eleven informative annexes.
