tables and design aids, as well as the AISC Specifications themselves. The 9th Edition of the Manual
contains welding design aids in Part 4 - Connections, including prequalified joint details, AWS welding
symbols, tables for eccentrically loaded fillet welds, and design examples. One is cautioned that the
welded prequalified joint tables are based upon AWS D1.1-88, and have been substantially revised in
subsequent editions of AWS D1.1. The 9th Edition ASD Manual is supplemented by a separate book,
Volume II - Connections. Chapter 2 contains general information regarding welding, Chapter 3 contains
design examples for Simple Shear Connections, Chapter 4 contains Moment Connections, and Chapter
6 contains Column Connections.
4. AWS SPECIFICATIONS AND STANDARDS.
a. D1.1 Structural Welding Code - Steel. ANSI/AWS D1.1 contains the requirements for fabricating
and erecting welded steel structures. The D1.1 Code is limited to carbon and low-alloy steels, of
minimum specified yield strength not greater than 690 MPa (100 ksi), 3.2 mm (1/8 in.) in thickness or
greater. It is not applicable to pressure vessel or pressure piping applications. D1.1 contains eight
sections: (1) General Requirements, (2) Design of Welded Connections, (3) Prequalification, (4)
Qualification, (5) Fabrication, (6) Inspection, (7) Stud Welding, and (8) Strengthening and Repair. It also
contains both mandatory and nonmandatory annexes, plus commentary. It is updated biannually, in even
years.
b. D1.3 Structural Welding Code - Sheet Steel. ANSI/AWS D1.3 covers arc welding of sheet and strip
steels, including cold-formed members that are equal to or less than 4.8 mm (3/16 in.) in nominal
thickness. Arc spot, arc seam, and arc plug welds are included in the Code. The D1.3 Code is applicable
when welding sheet steels to other sheet steels, or when welding to other thicker structural members.
With the latter application, the use of AWS D1.1 is also required for the structural steel. The D1.3 Code
contents are similar to AWS D1.1, except Sections 7 and 8 are not included.
c. D1.4 Structural Welding Code - Reinforcing Steel. ANSI/AWS D1.4 covers the welding of
reinforcing steel, as used in concrete construction. Welding of reinforcing steel to reinforcing steel, and
reinforcing steel to other carbon and low-alloy steels, is covered. With the latter application, the use of
AWS D1.1 is also required for the structural steel. D1.4 follows a different organizational structure than
AWS D1.1 and D1.3, and includes the following sections: (1) General Provisions, (2) Allowable Stresses,
(3) Structural Details, (4) Workmanship, (5) Technique, (6) Qualification, and (7) Inspection, plus
annexes.
d. A2.4 Standard Symbols for Welding, Brazing and Nondestructive Testing. ANSI/AWS A2.4
contains standards for the application of welding symbols on structural design and detail drawings, as
well as examples of their use. Part A of the document covers Welding Symbols, Part B covers Brazing
Symbols, and Part C covers Nondestructive Examination Symbols. The symbols and use specified in
this document supersedes symbols that may be shown in other AWS and industry documents, as they
may be incorrect or outdated in the other documents.
e. A5-series Filler Metal Related Specifications. ANSI/AWS A5-series documents establish the
requirements for electrodes, fluxes, and shielding gases, as applicable, for given general types of
electrodes and given welding processes. The requirements include, as applicable, chemical composition
of the electrode, moisture content, usability, markings, packaging, storage, certifications, and the as-
tested mechanical properties (strength, ductility, and toughness) and soundness of weld metal. An
Appendix or Annex is provided to explain the provisions and provide additional information. The A5-
