AS/NZS A1 Structural steel welding – Part 1: Welding of steel structures: Amendment 1. Correction amendment declared by Standards Australia to. AS/NZS Structural steel welding Part 1: Welding of steel structures; AS/NZS Structural steel welding Part 3: Welding. This Standard specifies requirements for the welding of steel structures made up of combinations of steel plate, sheet or sections, including hollow sections and.

In particular, due consideration shall be given to the control of emitted fumes, especially when welding through paints, primers and other surface coatings. The two weld categories shall be designated as follows: 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.
Licensees are permitted to use the Product the following extent: These designations are now consistent for all welding processes for which the harmonized ISO system has been applied. In welds made from two sides, specimens shall be taken from the first welded side.
Materials, fabrication and construction Welding consumables—Rods, wires and deposits for tungsten inert gas welding of non-alloy and fine-grain steels—Classification Qualification testing of welders—Fusion welding Part 1: 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.
The specimen shall comply with Table 4. Provided each preparation complies with the requirements of Table E2, Appendix E, for double-V, double-bevel, double-U or double-J welds, preparations of unequal depth shall be deemed prequalified also.
Some consumables may have classifications that vary from that shown. For deep penetration fillet welds made by fully automatic arc welding processes, provided that it can 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.
Temporary backing material of any type may be used for welds, provided the finished weld complies with the requirements of this Standard. Flame cutting of steels Technical Note 6: Transverse guided bend test Method 5. Instructions for the qualification of welding procedures on steels not listed in Clause 2. The following are represented on Committee WD Thus, such instructions should be agreed between the fabricator and principal. The nominated representative should be suitably qualified to deal with the technical issues of this Standard.

For system A classified consumables, consumables of the former positional class D are equivalent to position designation 3 including 4 and P are equivalent to designation 1 including 2 to 5. Variations to the equipment requirements may be used upon agreement with the principal. Where matching weathering properties are required, refer to Table 4.
Completed welds shall be visually examined and tested in the as-welded condition as specified in Table 4. This Sturctures, 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 with the different types of service to which the welds are subjected.

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 do not need to be repaired or rewelded; provided that, for any such defect, such sreel of assessment are acceptable to both the principal and the fabricator [see Paragraph B5, Appendix B and Appendix D, Item v ].
Diver-welders and welding operators for hyperbaric dry welding Licensed to Mr Vijai Moorthy on 31 March Where routine testing reveals imperfections requiring further consideration in accordance with Section 6, Clause 6.
Documents referenced for informative purposes are listed in the Bibliography. The inspector shall make a careful and systematic check to ensure that no welds called for in the drawings are omitted.
It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. See Appendix D, Items tx and shructures. See Appendix D, Items g and h.
Flux fused in the welding process shall not be re-used. Weldability of steels Technical Note 3: To maintain their currency, all Standards are periodically reviewed, and new editions are published. Filters for protection against radiation generated in welding and allied operations Hot-rolled steel flat products Cold-rolled, unalloyed, steel sheet and strip Welding cables Qualification of welders for fusion welding of steels Structural steel—Hot-rolled plates, floorplates and slabs All reports, including calculations for fracture mechanics assessments of defective welds, shall be retained and made available for information purposes.
Test reports that may be used for revalidation or prolongation of welder qualification should include WPS number, date welded and welder identification.
Guidance as to the extent of non-destructive examination is given in Table 7. 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. The objective of this Standard 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.
The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected. We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or welving.
