    Abstract - (Show below) - (Hide below)

    Specifies requirements for materials, welding consumables, welding processes, weld preparations, qualifications of welding procedures and personnel, and fabrication and inspection for the construction and maintenance welding of pipelines down to 3.2 mm wall thickness designed and constructed in accordance with AS 2885.1. The welding of pipelines with wall thickness less than 3.2 mm is not precluded but is not expressly covered by this Standard.

    Scope - (Show below) - (Hide below)

    This Standard specifies materials, welding consumables, welding processes, weld preparations, qualifications of welding procedures and personnel, and fabrication and inspection requirements for the construction and maintenance welding of carbon and carbon-manganese steel pipelines down to 3.2 mm wall thickness designed and constructed in accordance with AS 2885.1. The welding of corrosion resistant alloy steel pipelines, or pipelines with wall thicknesses less than 3.2 mm is not precluded but is not expressly covered by this Standard. The welding of such pipelines has to be given special consideration.The welding may be done by a manual metal arc, submerged arc, gas tungsten arc, gas metal arc, flux cored arc, oxyacetylene, or by a combination of these using a manual, semiautomatic, or automatic welding technique or a combination of these techniques. The welds may be produced by position or roll welding or by a combination of position and roll welding.
