AWS D1.1/D1.1M:2020 Structural Welding Code – Steel (Paperback)

AWS D1.1/D1.1M:2020 Structural Welding Code – Steel is the American Welding Society’s code for welded steel structures, in the AWS paperback edition for welders, inspectors, fabricators, and engineers.

D1.1 is the most widely referenced welding code in the United States. It covers design of welded connections, prequalified and qualified welding procedures, welder and operator qualification, fabrication, and inspection for structures built from carbon and low-alloy steels. Clauses 1 through 11 form the body of the code, supported by eight normative and eleven informative annexes. Building codes and AISC specifications invoke it by reference, which is what makes it a legal requirement on most steel jobs.

What's included

• AWS D1.1/D1.1M:2020, Structural Welding Code – Steel, complete text, paperback
• Publisher: American Welding Society (AWS)
• ISBN-13: 9781643220871

• Normative and informative annexes including acceptance criteria and sample forms

Who it's for

Candidates for the AWS Certified Welding Inspector (CWI) exam, where D1.1 is the most common Part C codebook. Also welding inspectors, QC managers, and fabricators in structural steel shops, structural engineers detailing welded connections, and contractors building to the International Building Code and AISC 360. Welding instructors and apprentices in structural programs use it as the reference for procedure and performance qualification.

Why this edition

AWS revises D1.1 on a five-year cycle, and the 2020 edition reorganized and updated provisions on processes, materials, and quality control compared with 2015. Many CWI exam candidates and job specifications still cite the 2020 edition, so it remains the working book in a large share of shops. If a contract or exam bulletin names a specific year, match it exactly; clause numbering shifts between editions and inspectors check by clause.

Frequently asked questions

Is AWS D1.1:2020 the edition used for the CWI exam?

The CWI Part C exam is offered on specific code editions. Confirm with AWS which D1.1 edition your exam date uses; 2020 has been the standard choice for several years.

What does D1.1/D1.1M mean?

The single book contains both US customary (D1.1) and metric (D1.1M) units. You do not need a separate metric edition.

Does D1.1 cover stainless steel or aluminum?

No. D1.1 is for carbon and low-alloy structural steel. Stainless is covered by D1.6 and aluminum by D1.2.
