Specifies requirements for the welding of steel structures subject to fatigue loading exceeding the range allowed by AS/NZS 1554.1, Structural steel welding, Part 1: Welding of steel structures.

This Standard specifies materials of construction, weld preparations and weld qualities, qualification of welding procedures and welding personnel, and fabrication nd inspection requirements for welds. It applies to fusion welding of steelwork in structures made up of combinations of steel plate, sheet, or sections, including hollowsections and built-up sections, or castings and forgings, by the following processes:(a) Manual metal-arc welding (MMAW).(b) Submerged-arc welding (SAW).(c) Gas metal-arc welding (GMAW).(d) Flux-cored arc welding (FCAW).(e) Electroslag welding (ESW) (including consumable guide).(f) Electrogas welding (EGW).The Standard is limited to the welding of steel parent material with a specified minimum yield strength not exceeding 450 MPa. The Standard applies specifically to the welding of steelwork in structures complying with AS 3990, AS 4100 or NZS 3404.1. Where the proportions of welded joints in these structures are governed by dynamic loading conditions, the Standard applies only to those welded joints which comply with the fatigue provisions of AS 3990 where the stress range in the welded joint is greater than 80% of the permissible stress range for Category B of AS 3990, or exceeds the stress range permitted for detail category 112 of AS 4100 or NZS 3404.1, but does not exceed the maximum stress ranges permitted for these categories.NOTE: Fillet welds and incomplete penetration butt welds may be used in AS 4100 or NZS 3404.1 detail category 125, and in Category B fatigue applications of AS 3990 when the direction of the weld is parallel to the direction of the applied stress. In addition to the abovementioned structures, the Standard applies to the welding of cranes, hoists, and other dynamically loaded structures; the welding of road and pedestrian bridges; and the welding of steelwork in applications other than structural. The Standard does not apply to the welding of structures by the following processes:(i) Gas welding (GW).(ii) Gas tungsten arc welding (GTAW).(iii) Resistance welding (RW).(iv) Friction welding (FW).(v) Thermit welding (TW).It also does not apply to the welding of pressure vessels and pressure piping. The Standard does not cover the design of welded connections or permissible stresses in welds, nor the production, rectification, or repair of castings.
