scope:

This Standard covers welding requirements for carbon and low-alloy welded steel construction, with the exception of those types listed in Clause 1.2.

Requirements that are essentially common to all such structures are covered in Clauses 3 to 10, while provisions applying specifically to statically-loaded structures and to cyclically-loaded structures are included in Clauses 11 and 12, respectively.

This Standard is not intended to apply to pressure vessels or to structures governed by special codes such as those of the American Petroleum Institute, the American Society of Mechanical Engineers, or the American Water Works Association.

This Standard includes provisions for the following:

(a) shielded metal arc welding (SMAW);

(b) submerged arc welding (SAW);

(c) gas metal arc welding (GMAW);

(d) gas tungsten arc welding (GTAW);

(e) flux-cored arc welding (FCAW);

(f) metal-cored arc welding (MCAW);

(g) electroslag welding (ESW);

(h) electrogas welding (EGW); and

(i) stud welding (SW) processes.

The provisions of this Standard are not intended for use with steels having a specified minimum yield strength over 700 MPa (100 000 psi).
