The decision tree does not show access to Tier 2 acceptance criteria from the workmanship standards of Tier 1. Source to film distance. Contact the department Website feedback If you have any queries or suggestions about this website, contact our Online Services Branch.

At times there may be a need for control of the operating pressure and flow rates in order to provide suitable conditions for welding. Two openings are not uncovered at the same time.

Method Charpy tests shall be carried out in accordance with AS The methods qs the requirements for qualifying welding procedures have been clarified. Tee butt welds qualify fillet welds as listed.

Australian experience, which formed the basis for the edition of this Standard, and the results of recent Australian research work undertaken by the CRC for Welded Structures have also been taken into account see also Preface. Cleaning after testing The penetrant and the xs shall be removed after testing.

Gas supply network safety and network supply standards

Reference reflectors shall be no larger than the maximum acceptable defects they simulate. Corporate Freedom of information guidelines, reports, policies, plans, and contact information. Any combination of electrodes and 285.2 may be used to qualify a procedure.


Where the weld complies with this Standard and the results have been recorded see Clause 8.

AS 2885.2 – Key Concepts and Application

The changes do not involve an increase in carbon equivalent of more than 0. Where the terminology and abbreviations used in AS do not adequately describe some of the discontinuities found in pipeline welds, additional descriptive abbreviations may be required e. The joint preparation shall be within specified tolerances for production, and should preferably be made by the same method as that used in production.

Item indicates the specification topic.

Final nondestructive examination shall be carried out not sooner than 285.2 h after completion of welding, followed by leak testing. Where the weld meets all the criteria of acceptance, and the results have been recorded see Clause 6. Before cutting the line pipe with a hot tapping tool, the weld and adjacent material should be leak-tested at a pressure 285.2 greater than the current internal pressure of the pipeline.

The assessment may be stopped at any stage when results are unsatisfactory.

The WELDNET – AS/NZS Review – Australian Welding Institute

This identification shall be clearly marked on the test piece adjacent to the weld. If the density in the parent metal falls within the range specified above but the required minimum for the weld metal is not met, then the weld reinforcement shall be ground in the regions of insufficient density and the radiograph s shall be retaken so that the above requirements are met.


Where a welder holds a Category 2 partial qualification and is required to qualify for a Category 1 multiple qualificationthe successful making of the appropriate additional test welds. The shallowest groove on the comparator shim shall be placed closest to the 28885.2.

Care shall be taken to prevent ignition due to electrical sparking see Clause The zs tensile test used in the previous Standard to 2885.2 whether overmatching is achieved has been deleted pending the performance of further research. The most important of these is that because the limits are based on experimentally validated plastic collapse considerations, the welds have to be shown to have adequate toughness in order to ensure that failure does not occur by brittle fracture.

Welds made by GMAW welding should be examined with mechanized ultrasonic testing. If the non-destructive examination did not reveal the discontinuity, or if no non-destructive examination was performed, the investigation shall be undertaken using metallography.

Image quality indicator wire visibility using this technique may be reduced by 1 in the first three rows. The most common test methods that are used to assess fracture toughness in pipeline girth welds are the Charpy test see AS Any combination of electrodes may be used to qualify a procedure.

Longitudinal welds or spiral welds made during the manufacture of a pipe or a component. It should be swabbed if necessary. Equipment consisting of the following:
