Description

Sets out requirements for the qualification of welding and brazing procedures, welders and brazers, and requirements for production weld testing other than non-destructive examination, when used in the manufacture, alteration and repair of boilers, pressure vessels, pressure piping and their components.

Scope

This Standard specifies requirements for the qualification of welding and brazing procedures, welders and brazers, and requirements for production weld testing other than non-destructive examination, when used in the manufacture, alteration and repair of boilers, pressure vessels, pressure piping and their components as specified in AS/NZS 1200, AS 1210, AS 1228 and AS 4041. See Figure 1 for a summary of the welding and brazing qualification process.
This Standard is intended for use by designers, manufacturers, welders, brazers, inspection bodies, inspectors, testing authorities and all persons concerned with the welding and brazing of pressure equipment.
This Standard may apply to automotive LP Gas fuel vessels (covered by AS/NZS 3509), serially produced pressure vessels (covered by AS 2971) or welded gas cylinders (covered by AS 2030.1), where specified by these Standards. This Standard does not apply to pipelines in accordance with AS/NZS 2885.2, except where referenced.
The Standard provides specific details for the following:
(a) Manual metal-arc welding, flux cored arc welding, gas metal-arc welding, gas tungsten-arc welding, submerged arc welding, plasma arc welding, electroslag welding and oxy-acetylene welding.
(b) Torch brazing, furnace brazing, induction brazing, resistance brazing and dip brazing.
(c) The welding and brazing of carbon, carbon-manganese, and low and high alloy steels; and copper, aluminium, nickel, titanium, zirconium and alloys of these materials.
(d) Welding procedure qualification.
(e) Welder qualification.
Specific details for stud welding, electron-beam welding, explosion welding, laser beam welding, electro-gas welding, fusion welding of plastics and friction welding processes are not covered by this Standard. For these, see ASME BPVC-IX or equivalent.
The principles established in this Standard may be used in the qualification of processes, materials and applications not covered by the scope outlined above (see also Clause 1.5 and Clause 1.6).
