The nominated representative should be suitably qualified to deal with the technical issues of this Standard. This Table identifies nearest equivalent designations. The main risk of tearing is with cruciform, T- and corner joints and with complete penetration welds where high levels of strain are known to occur in the through-thickness direction in the element to which the connection is made.

All reports, including calculations for fracture mechanics assessments of defective welds, shall be retained and made available for information purposes.

Where this is not possible, additional gain shall be added in accordance with Table 6. The system A classification though remains consistent with the method used for other consumables types. Where the manufacturer makes specific recommendations covering conditioning strhctures pretreatment of flux prior to use, such recommendations shall be followed.

Macro metallographic test for cross-section examination Method 6.

This is largely due to the ISO based classifications for most processes adopting similar strength, impact resistance and hydrogen control designations. Home As NZS Where the joint contains two welds, the size shall be the combined depths.

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.

However, where it can az demonstrated, by the use of fracture mechanics or other suitable methods of assessment, that the defects will not be injurious to the performance of the structure, weoding defects do not need to be repaired or rewelded; provided that, for any such defect, such methods of assessment are acceptable to both the principal and the fabricator [see Paragraph B5, Appendix B and Appendix D, Item v ]. Where such penetration is achieved, the size of the weld may be correspondingly reduced.

Type of weld Usage Butt throughout Fillet throughout Used in any joint Used only where diameter of smaller member is less than one-third of that of larger member Combination of butt and fillet with Used in any joint gradual transitions between them b Partially or fully flattened Where the end of a circular hollow section member is partially flattened to a suitable shape, Items a i and a ii above shall apply and, for the application of Item a iithe diameter of the flattened portion of the section shall be measured in a plane perpendicular to the axis of the main section, the plane being taken at the point of intersection of the axis of the branch section with the weldinf of the main section.

Electrodes that do not comply with the above Standards may be used, provided they are qualified in accordance with the requirements of Clause 4. The changes required by the Amendment are indicated in the text by a marginal bar and amendment aa against the clause, note, table, figure or part thereof affected.

The following are represented on Committee WD This Standard was published on 25 November The ends of the slot shall be semicircular or shall have the corners rounded to a radius of not less than the thickness of the part containing it, except for those ends that extend to the edge structure the part. Where seal welding is required, Clause 3. Guidance on the selection of welding consumables suitable for weathering steel not listed in Table 4. This Standard does not apply to underwater welding.

We are a non-profit group that run this website to share documents.

The inspector shall have access at all reasonable times to all relevant phases of the work, and shall be given reasonable notice in advance of the start of welding operations. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover. In welds 15554.1 from two sides, specimens shall be taken from the first welded side.

See Appendix D, Item t and v. Care should be taken in applying this Table to imported steels as verification tests may be required. On the completion of the test, the dimension of any crack or other defect in the weld or the heat-affected zone shall be not greater than 3 mm, measured in any direction at the outer surface of the test specimen.

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 shructures weld quality assurance associated with the different types of service to which the welds are subjected.

Prequalified joint preparations, welding consumables and welding procedures are also given in the Standard. Fire precautions Part 2: Diver-welders and welding operators for hyperbaric dry welding Licensed to Mr Vijai Moorthy on 31 March Electrical Certification of welders and welding supervisors See Strutures D, Item k.

The transition slope between the parts shall be not steeper than 1: Transverse butt tensile test Method 3.

Where the mechanical properties of the transverse butt tensile test meet the minimum requirements shown in Table 4. Please copy and paste this embed script to where you want to embed Embed Script. See Appendix D, Items t and u.

Parent metal discontinuities which interfere with the examination should be reported to the principal and included in the test report. The minimum centre-to-centre spacing in a longitudinal direction zs any line shall be two times the length of the slot.

Completed welds shall be visually examined and tested in the as-welded condition as specified in Table 4. For MMAW consumables, 1554.1 situation is weldin complex as impact energy requirements for system B classified consumables follows the current AWS practice of defining minimum requirements for each electrode class and composition. Control of lamellar tearing Technical Note strcutures This Standard incorporates Amendment No.

Report “As NZS 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. To extend the validity of weld procedures qualified under previous classification systems to utilize consumables classified under the harmonized ISO based classification system, the procedure described in this Appendix sfructures be adopted, and where contractually required, agreed between the fabricator and principal prior to the commencement of welding to minimize the need for the fabricator to requalify weld procedures.

We need your help to maintenance this website. Low and intermediate alloy steel electrodes for manual metal-arc welding of carbon steels and low and intermediate alloy steels superseded In addition, the joint preparations shown in Figure 4.

Shear probes shall have a dominant frequency in the range 2.
