AWS Releases Newest Structural Welding Code – Steel
The American Welding Society (AWS) announces the release of D1.1/D1.1M:2025, Structural Welding Code – Steel (D1.1/D1.1M), the latest edition of AWS’ flagship structural welding code. Originally developed in 1928 as the “Code for Fusion Welding and Gas Cutting in Structural Steel” to standardize welding in building construction applications, D1.1/D1.1M has since become the globally recognized benchmark for structural welding requirements. Almost a century later, it remains the welding industry’s definitive resource for engineers, fabricators, and inspectors.
The D1.1/D1.1M code outlines requirements for welded structures made from carbon and low-alloy constructional steels, providing essential guidelines that influence the design, fabrication, qualification and inspection of steel structures worldwide. The 2025 edition includes key updates that reflect advancements in materials, techniques, and industry best practices.
“D1.1/D1.1M has been the foundation of structural welding for close to a hundred years, adapting to industry innovations while maintaining its quality and precision,” said Jennifer Molin, Director, Standards Committee Operations. “This latest edition ensures that the industry has access to the most current guidelines, reinforcing best practices in structural welding.”
Key Highlights of D1.1/D1.1M:2025:
- Comprehensive updates to material classifications and welding procedures
- Enhanced guidelines for weld quality, inspection, and fabrication.
- Clarifications and modifications to existing provisions to improve usability.
- Updates based on industry feedback and evolving best practices
D1.1/D1.1M:2025 is now available for purchase both in hard copy and as a digital download through the AWS Bookstore.
