AS/NZS 1554.6:2012 PDF Download

AS/NZS 1554.6:2012 is a standard that specifically addresses the welding of stainless steel structures for structural purposes. It outlines the requirements for the welding processes to be used, including manual metal arc welding (MMAW), submerged arc welding (SAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and plasma arc welding (PAW).

The standard applies to structures made up of stainless steel plate, sheet, sections (such as hollow sections and built up sections), castings, and forgings. It also applies to structures that comply with appropriate standards and have welded joints subjected to dynamic loading conditions.

AS/NZS 1554.6:2012 covers various aspects of the welding process. It specifies materials of construction, weld preparations, and weld qualities. It also outlines requirements for surface finish, qualification of welding procedures and personnel, fabrication, and inspection requirements for welds. The standard applies to all stainless steel fabrication, including applications that require aesthetic, hygienic, or other non-structural purposes.

It is important to note that the standard includes waveform controlled welding techniques, such as "synergic," "programmable," and "microprocessor controlled" processes, which encompass pulsed spray transfer and controlled short circuit transfer methods, within the scope of gas metal arc welding (GMAW).
