This Standard specifies requirements for the welding of stainless steel structures made up of combinations of stainless steel plate, sheet, sections, including hollow sections 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) Gas tungsten arc welding (GTAW).

(e) Flux cored arc welding (FCAW).

(f) Plasma arc welding (PAW).

The Standard applies to the welding of steelwork in structures complying with appropriate Standards. Where welded joints are governed by dynamic loading conditions, the Standard applies to those welded joints that comply with the fatigue provisions of the relevant application Standards.

The Standard prescribes materials of construction, weld preparations and weld qualities, surface finish, qualification of welding procedures and welding personnel, and fabrication and inspection requirements for welds related to all stainless steel fabrication including aesthetic, hygienic or other non-structural applications.

NOTE: GMAW includes waveform controlled welding such as "synergic", "programmable", and "microprocessor controlled" processes' e.g. pulsed spray transfer, controlled short circuit transfer.
