AWS D1.1 - D1.1M-2020 errata 2023 PDF

Full title and description

St AWS D1.1 / D1.1M:2020 — Structural Welding Code — Steel, including the official errata issued in 2023. This publication is the 2020 edition of the American Welding Society's primary code for welding steel structures, provided in dual units (metric and imperial) and updated by the 2023 errata to correct typographical, editorial, and limited technical clarifications issued after initial publication.

Abstract

The AWS D1.1 / D1.1M:2020 standard establishes the requirements for welding of structural steel used in buildings, bridges, and other structures. The document provides requirements for qualification of welding procedures and personnel, materials, fabrication, inspection, and acceptance criteria. The 2023 errata corrects errors and clarifies select provisions from the 2020 edition to ensure consistent interpretation and application of the code.

General information

• Status: Current edition with errata (2020 edition, errata issued 2023)
• Publication date: 2020 (with official errata published in 2023)
• Publisher: American Welding Society (AWS)
• ICS / categories: 25.160.01 (Welding) / Construction and structural engineering standards
• Edition / version: D1.1 / D1.1M — 2020 edition; errata 2023
• Number of pages: Approximately 300–400 pages (varies by format and inclusion of commentary)

Scope

AWS D1.1 / D1.1M:2020 covers welding requirements for carbon and low-alloy steels, specifying requirements for weld design, fabrication, welding procedures, welder and operator qualification, preheat and interpass temperatures, nondestructive and destructive testing, and acceptance criteria for discontinuities. It applies to shop and field welding of structural components used in buildings, bridges, and other civil and industrial structures. The errata 2023 corrects identified errors and provides clarifications to ensure the code’s correct application without changing substantive technical intent.

Key topics and requirements

• Qualification of welding procedures (WPS/PQR) and welders/operators
• Design and detailing of welded connections and joints
• Preheat, interpass temperature, and post-weld heat treatment requirements
• Welding processes, consumable selection, and joint preparation
• Inspection and testing: visual, radiographic, ultrasonic, magnetic particle, and destructive testing
• Acceptance criteria for discontinuities and repair requirements
• Requirements for fabrication tolerances, fit-up, and alignment
• Specific provisions for fatigue, fracture-critical members, and cyclic loading where applicable

Typical use and users

This standard is used by structural engineers, fabricators, welding engineers, inspectors, construction contractors, and qualification bodies. It is referenced in contract specifications, building and bridge design, welding procedure development, welder qualification testing, quality assurance programs, and regulatory compliance for welded steel structures.

Related standards

Commonly referenced and related documents include other AWS D1 series codes (for example D1.3 for sheet steel, D1.5 for railroad vehicles), ASTM standards for steel materials and testing, ISO and EN welding standards for material and testing equivalence, and project- or jurisdiction-specific building and bridge codes that adopt or reference AWS D1.1.

FAQ

Q: What is this standard?

A: AWS D1.1 / D1.1M:2020 is the American Welding Society’s Structural Welding Code for steel, providing requirements for welding of structural steel in both imperial and metric units. The 2023 errata contains corrections and clarifications issued after the 2020 publication.

Q: What does it cover?

A: It covers welding procedure and welder qualification, materials, joint design and fabrication, preheat and interpass temperatures, testing and inspection methods, and acceptance criteria for welded structural steel.

Q: Who typically uses it?

A: Structural engineers, welding engineers, fabricators, inspectors, contractors, and agencies responsible for the design, fabrication, and inspection of welded steel structures.

Q: Is it current or superseded?

A: The document described is the 2020 edition with the official errata released in 2023. Users should verify whether a newer full edition or additional errata/corrigenda have been issued since 2023 before applying the standard.

Q: Is it part of a series?

A: Yes. AWS D1.1 is part of the AWS D1 series, which includes related codes for other materials and applications (for example D1.2, D1.3, D1.5), and it often references other AWS and industry standards.
