AWS D1.1/D1.1M:2020 – Structural Welding Code – Steel is the 24th edition of the code and serves as the definitive standard for welding carbon and low-alloy steel structures. Approved by ANSI and published by the American Welding Society, it reflects the latest best practices in structural welding design, fabrication, and inspection.

Highlights:

• Welding requirements for carbon and low-alloy steels
• Design criteria for welded joints in tubular and nontubular members
• Prequalification standards for Welding Procedure Specifications (WPS)
• Qualification tests for welding procedures and personnel
• Rules for fabrication, inspection, repair, and stud welding
• Guidance for strengthening and retrofitting existing structures
• Covers steel 1/8 in [3 mm] or thicker, up to 100 ksi [690 MPa] yield strength
• Includes mandatory clauses, normative and informative annexes, and detailed commentary

Who It’s For:
Structural engineers, welders, inspectors, and contractors engaged in the design, construction, and quality control of welded steel structures in buildings, bridges, towers, and industrial facilities.
