Scope:to the welded modification or repair of existing steel This code contains the requirements for fabricating welded steel structures. When conformance to the Code is stipulated in contract documents, all provisions of this code shall be complied with, except for those provisions that the Engineer or contract documents specifically exempt.
The following is a summary of the code sections:
1. General Requirements. This section contains basic information on the scope and limitations of the code.
2. Design of Welded Connections. This section contains requirements for the design of welded connections composed of tubular, or nontubular, product form members.
3. Prequalification. This section contains the requirements for exempting a WPS (Welding Procedure Specification) from the qualification requirements of this
4. Qualification. This section contains the qualification requirements for WPSs and welding personnel (welders, welding operators and tack welders) necessary to perform code work.
5. Fabrication. This section contains the requirements for the preparation, assembly and workmanship of welded steel structures.
6. Inspection. This section contains criteria for the qualifications and responsibilities of inspectors, acceptance criteria for production welds, and standard procedures for performing visual inspection and NDT (nondestructive testing)
7. Stud Welding. This section contains the requirement for the welding of studs to structural steel. 8. Strengthening and Repair of Existing Structures. This section contains basic information pertinent structures.
Limitations. The code is not intended to be used for the following:
(1) Steels with a minimum specified yield strength greater than 100 ksi (690 MPa)
(2) Steels less than 118 in. (3.2 mm) thick. When base metals thinner than 118 in. thick are to be welded, the requirements of ANSVAWS DI .3 should apply. When used in conjunction with ANSVAWS D1.3, conformance with the applicable provisions of this code shall be required.
(3) Pressure vessels or pressure piping
(4) Base metals other than carbon or low-alloy steels
