Structural Welding Code—Steel
Published by American Welding Society (AWS), 12/09/2019
AWS D1.1/D1.1M, 24th Edition – Structural Welding Code—Steel
AWS D1.1 is a widely recognized standard for the welding of structural steel. Developed by the American Welding Society (AWS), this standard provides guidelines for the design, fabrication, and inspection of welded structures made from carbon steel and low-alloy steel.
The purpose of AWS D1.1/D1.1M is to ensure the quality and safety of welded structures through the use of approved welding procedures and qualified welders. This standard covers a wide range of topics, including welding procedures, welder qualification, material properties, joint design, and inspection requirements.
AWS D1.1/D1.1M is used in a variety of industries, including construction, manufacturing, and transportation. It provides a framework for the design and fabrication of welded structures that meets industry standards and regulatory requirements.
By following the guidelines set forth in AWS D1.1/D1.1M, engineers, manufacturers, and inspectors can ensure the quality and safety of welded structures. This standard helps to prevent welding failures and ensures that welded structures are able to withstand the stresses and forces they will encounter in their intended applications.
This code contains the requirements for fabricating and erecting welded steel structures. When this code is stipulated in contract documents, conformance with all provisions of the code shall be required, except for those provisions that the Engineer (see 1.5.1) or contract documents specifically modifies or exempts.
The following is a summary of the code clauses:
1. General Requirements.
This clause contains basic information on the scope and limitations of the code, key definitions, and the major responsibilities of the parties involved with steel fabrication.
2. Normative References.
This clause contains a list of reference documents that assist the user in implementation of this code or are required for implementation.
3. Terms and Definitions.
This clause contains terms and definitions as they relate to this code.
4. Design of Welded Connections.
This clause contains requirements for the design of welded connections composed of tubular, or nontubular, product form members.
5. Prequalification of WPSs.
This clause contains the requirements for exempting a Welding Procedure Specification (WPS) from the WPS qualification requirements of this code.
This clause contains the requirements for WPS qualification and the performance qualification tests required to be passed by all welding personnel (welders, welding operators, and tack welders) to perform welding in accordance with this code.
This clause contains general fabrication and erection requirements applicable to welded steel structures governed by this code, including the requirements for base metals, welding consumables, welding technique, welded details, material preparation and assembly, workmanship, weld repair, and other requirements.
This clause contains criteria for the qualifications and responsibilities of inspectors, acceptance criteria for production welds, and standard procedures for performing visual inspection and nondestructive testing (NDT).
9. Stud Welding.
This clause contains the requirements for the welding of studs to structural steel.
10. Tubular Structures.
This clause contains exclusive tubular requirements. Additionally, the requirements of all other clauses apply to tubulars, unless specifically noted otherwise.
11. Strengthening and Repair of Existing Structures.
This clause contains basic information pertinent to the welded modification or repair of existing steel structures.
