If the weld does not comply, the location and extent of the defects shall be given. The stewl angle shall be the actual measured angle, not the nominal angle. The centre-to-centre spacing between plug welds shall be not less than four times the diameter of the hole. Diver-welders and welding operators for hyperbaric dry welding Licensed to Mr Vijai Moorthy on 31 March For the purpose of this requirement, a digital or scanned image is considered to be the equivalent of a photograph.
Provided that the fabricator has included sufficient information to correctly identify the trade name and previous classification of consumables used to qualify their weld procedures, the procedure tests do not need to be repeated with the adoption of the ISO based classification system.
Electrodes that do not comply with the above Standards may be used, provided they are qualified in accordance with the requirements of Clause 4.
International Involvement Standards Australia and Standards New Zealand are responsible for ensuring that the Australian and New Zealand viewpoints are considered in the formulation of international Standards and that the latest international experience is incorporated in national and Joint Standards. Flame cutting of steels Technical Note 6: For the purposes of Table 6.
The intention is that the designer select the category suited to the severity of the service and nominate this on the drawings. Any recommendations of the manufacturer, covering protection during storage and use, conditioning and pretreatment of electrodes or filler wires prior structurs use, shall be followed. When applying these thickness limitations, an adjustment to the minimum preheat temperature may be required see Clause 5. We need your help to maintenance this website.
Licensees are permitted to use the Product the following extent: Reissued incorporating Ot No. Where the weld is full size throughout its length, no reduction in effective length shall be made for either the start or crater of the weld.
This Standard was published on 25 November Get permission to copy from this publication www. See Appendix D, Item w. Where welded joints in these structures are governed by dynamic loading conditions, this Standard applies only to those welded joints that comply with the fatigue provisions of ASAS or NZS Consumables with T selding, no limitation on arc energy for single-run or two-run technique.
These designations are now consistent for all welding processes for which the harmonized ISO system has been applied. Where a consumable is not prequalified in accordance with Items abc d or e above, but the fabricator can produce relevant data, properly documented, of satisfactory prior experience in the use of the consumables with a qualified procedure, the data shall be taken as sufficient evidence for deeming the consumable qualified for that procedure [see Clause 4.
The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources.

Compression probes shall have a dominant frequency in the range 4 MHz to 5 MHz, and an essentially square or circular transducer in the size range 10 mm to 20 mm. If any failure is due to cracking in the heat-affected zone or in the weld, the procedure shall be modified and a new procedure test plate shall be prepared. Licence Agreement Legislation; 3.

See Appendix G for guidance on the relationship between these steels and material group numbers utilized in other Standards. Provided each preparation complies with the requirements of Table E1 for double-V, double bevel, double-U and double-J welds, preparations of unequal depth shall be deemed prequalified also.
Repaired welds shall be reinspected to the same level as that originally specified. The main area of change affects ax former type 12 and 13 designations which will now become type 13 although some type 13 consumables with good impact resistance due to the presence of basic minerals in structurez flux coating will most likely weldng classifiable as a type In welds made using self-shielded flux cored consumables in combination with other consumable types see Clause 4.
Either— i the steel type number, as given in Table 4. The effective area of a slot weld shall be as for a fillet weld of the same size and effective length.
All new WPS documents should then srtuctures to this modified classification. Complete penetration butt welds that are to be welded from both sides using these prequalified preparations shall have the roots of the weld gouged out by suitable means to sound metal, before welding is started on the second side, unless evidence is produced by macro etching that complete fusion can be obtained without such gouging.
Where a non-destructive examination is specified, the drawings or other documents shall clearly state the methods to be used and the extent of testing to be carried out see also Clause 3.
