It is used as replacement for long bolts as well as for concrete anchors and foundation bolts. However, where it can be 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, such defects need not 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.

The welding supervisor shall ensure that all welding is carried out in accordance with the plans, the specifications, any other documents and the requirements of this Standard.

The Standard does not address the issue of weld-metal cold cracking. Due to changes in the welding consumable classifications systems used in Australia and New Zealand, reference should be made to Appendix F for guidance on the extension of weld procedure qualification.

Details of typical compound welds are shown in Figure 3. Home As NZS For workmanship tolerances of weld preparations, see Table 5. It is recommended that the fabricator treat such joints as if they had been welded with non-prequalified welding consumables. Surfaces to be welded and surfaces adjacent to a weld shall also be free from loose or thick scale, slag, rust, grease, paint or other foreign matter that could prevent proper welding.

The inspector ss make a careful and zns check to ensure that no welds called for in the drawings are omitted. Guidance on the minimum technical knowledge requirements for Items efg and h is provided in AS The Charpy V impact test temperature of the other steel is not colder than that of the steel used in the qualified procedure. Specifying weld sizes larger than necessary shall be avoided.

Where seal welding is required, Clause 3. Where routine testing reveals imperfections requiring further consideration in accordance with Section 6, Clause 6.

Concurrent Users means the maximum number of people able to access the Product at any one time, and is limited to the number of Licences purchased. The welding supervisor shall have a minimum of three years experience in the fabrication of welded structure and shall comply with one or more of the following: NZS includes additional requirements limiting the heat input in the deposited weld metal for welds subject to The simplest level of procedures is the SWMS system. Instructions for the qualification of welding procedures on steels not listed in Clause 2.

Temporary welds and attachments shall not be allowed on the tension flanges of beams, girders and similar members.

Where matching weathering properties are required, refer to Table 4. The permitted heat input range see Clauses 4. Premature failure at the corners of the 155.1 specimen shall not be considered cause for rejection. Inspection aids and measuring devices shall be sufficient to enable the inspector to detect imperfections that could occur on welds and test pieces.

Criteria for the selection of the appropriate level of quality requirements Part 2: The fabricator shall provide evidence acceptable to the principal that the welders are suitably qualified.

The objective of this Nas is to provide rules for the welding of a wide range of steel constructions, and while it is expected that its main use will be for statically loaded welds, it applies also to some welds subject to fatigue. Prequalified joint preparations, welding consumables and welding procedures are also given in the Standard.

It nnzs weld defects such as cracks, undersize, undercut and porosity for example. When applying this mzs for single-run and multi-run fillets, consideration shall be given to the pre-heat requirements for combined thicknesses of T1, T2 and T3, and the pre-heat requirements for the combined thicknesses shall be shown on the welding procedure specification WPS and on the procedure qualification record PQR.

The principal may require nzx a welding procedure for repairs be qualified and approved. Ze a For material nzd a thickness of less than 36 mm, Item o of Table 4. Any segment of intermittent fillet weld shall have an effective length of not less than 40 mm. Where flux is re-used, flux-recycling systems shall include suitable sieves and magnetic particle separators and shall be such that the flux remains in a satisfactory condition for re-use.

Misalignement of plates of equal thickness see Clause 5. Welds nominated as Category SP, but not complying with the requirements of that category, may be considered as Category GP welds, provided the requirements of the design Standard are satisfied and the principal has agreed. Temporary backing material of any type may be used for welds, provided the finished weld complies with the requirements of this Standard.

In addition, the requirements of Clauses 4. Development and Research of Eccentrically Braced Frames with Replaceable Active Links Ductile eccentrically braced frames designed in accordance with the New Zealand Steel Structures Standard, NZSprovide life safety during a design level or greater earthquake; however, nss eccentrically braced frame active link may su Ss following are deemed to comply with this requirement: The weld and adjacent base metal shall be cleaned by brushing or other suitable means.

For deep penetration fillet welds made by fully automatic arc welding processes, provided that it ad be demonstrated by means of a macro test on a production weld that the required penetration has been achieved, an increase in design throat thickness shall be allowed as shown in Figure 3.
