Specifying weld sizes larger than necessary shall be avoided. Home As NZS The nominated representative should be suitably qualified to deal with the technical issues of this Standard.

The inspector shall make a careful and systematic check to ensure that no welds called for in the drawings are omitted. A completed welding procedure sheet WPStogether with records of tests carried out constitutes documentary evidence of prior experience.

Where there is a root gap, the size shall be given by the lengths of the legs of the inscribed triangle, reduced by ws amount shown in Table E3, Appendix E.

AS/NZS – Standards Australia

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.

Licensee means the purchaser and user of the Product. It is greatly increased where free movement is restrained by other portions of the structure. Control of lamellar tearing Technical Note 7: Care should be taken in applying this Table to imported steels as verification tests may be required.

See Appendix D, Items g and h. 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. Instructions for the qualification of welding procedures on steels not listed in Clause 2. Where a consumable is not prequalified in accordance with Items abc d or e above, but the fabricator can produce relevant data, properly documented, wrlding satisfactory prior experience in the weldinv of the consumables we,ding a qualified strucutres, the data shall be taken as sufficient evidence for deeming the consumable qualified for that procedure [see Clause 4.


For other situations where equivalency cannot be established, the weld procedure should be requalified in accordance with the requirements of this Standard. Weldability of steels Technical Note 3: For the purposes of Table 6. Repaired welds shall be reinspected to the same level as that originally specified.

Completed welds shall be visually examined and tested in the as-welded condition as specified in Table 4. Fracture mechanics Technical Note No change is required. The minimum spacing of lines of slot welds in a direction transverse to their length shall be four times the width of the slot. See Appendix D, Items t and u.

Where seal welding is required, Clause 3. Guidance on appropriate post weld heat treatment may be found in AS This Standard, in catering for structures subject to fatigue conditions as well as statically loaded structures, provides two categories of welds with two differing levels of weld quality assurance associated 1554. the different az of service to which the welds are subjected.

With the exception of quenched and tempered steels, parent materials not identified to a Standard nominated in Item c above may be used, provided one of the following requirements is met: Some consumables may have classifications that vary from that shown.

Where imperfections in excess of the limits in Table 6. All new WPS documents should then refer to this modified classification. For welds on material with a thickness of more than 50 mm, evaluation shall be carried out at Level 3.


The extent, type and control of this documentation should be agreed prior to the commencement of the work see Appendix D.

wflding It should then involve a progressive reduction in frequency of testing, on the basis of achieving compliance with each test. They should comply with the following, as appropriate: Joint identification Close-joint square butt weld, welded both sides Manual metal-arc Submerged arc t 3 max. Such variations include transducer sizes and frequencies. A welding procedure specification shall be developed from the PQR, based on the limits of the essential variables of Clause 4.

The appropriate steel type, suitable for the design service temperature and material thickness, shall be selected in accordance with Paragraphs B4.

See Appendix D, Item d. Welding of steel structures subject to high levels of fatigue loading Macro metallographic test for cross-section examination Method 6. This Standard requires that weld preparations, welding consumables and welding procedures be qualified before commencement of welding. Single-run and multi-run fillet welds may be qualified on opposite sides of the same test plates. T-joints by other portions of the Medium restraint: See Appendix G for guidance on the relationship between these steels and material group numbers utilized in other Standards.

For plate thicknesses of less than 15 mm, the transducer size may be reduced to 8 mm and frequencies increased to 5 MHz.
