The effective area of a plug weld shall be the nominal cross-sectional area of the hole in the plane of the faying or contact surface. Aids to visual examination may be used wherever necessary to facilitate the assessment of an az.
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 The main area of change affects the 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 the flux coating will most likely be classifiable as a type Joint identification B-C 1a Joint type Manual metal-arc 3 max.
Guidance as to the extent of non-destructive examination is given in Table 7. The Standards Council of New Zealand is the national authority responsible for the production of Standards.

Using the joint weldability index from Item c above, obtain the combination of arc energy and minimum preheating temperature from Figure 5. Correction of distortion see Clause 5. Health and safety in welding Technical Note Flame cutting of steels Technical Note 6: It should then involve a progressive reduction in frequency of testing, on the basis of achieving compliance with each test.
Number of welds per procedure One Macro etch samples See Table 4. Repairing or rewelding shall be carried out in accordance with this Standard and the principal shall nzd advised of all such repairs. The surfaces shall be cleaned thoroughly before welding. Ze a The steel grade shall be selected by either the notch-ductile range method as specified in Paragraph B2 or using a fracture assessment as specified in Paragraph Nzw.
The following are represented on Committee WD Prior to and during welding, the inspector shall inspect the set-up of the work and ensure that— a b c welds are in accordance with the drawings; the welding is carried out on the specified material with suitable equipment; correct procedures are maintained; and the work is performed in accordance with the requirements of this Standard.
The total arc energy for the process is the sum of all arc energies for each individual arc. The transition shall be made by chamfering the thicker part or by sloping the weld surfaces, or by any combination of these as shown in Figure 3.
Welding to AS/NZS of Boron Containing Steel
Where a structure contains both categories, this nomination of appropriate categories will ensure that appropriate levels of supervision and inspection will be applied to the relevant parts of the structure.
Placing pieces of metal in the root gap for bridging the gap is not permitted.
Qualification of NDE technicians see Clause 7. 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.
Care should be taken in applying this Table to imported steels as verification tests may be required. This is a greatly misunderstood area and we would love to help you manage it. 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.
A procedure qualification on a single bevel butt weld that has been welded from only the one side shall qualify for welding a double bevel butt weld and a single bevel butt weld 154.1 has been welded on both sides. A repair weld procedure may be required in such instances. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options.
Inspection aids and measuring devices shall be sufficient to enable the inspector to detect imperfections that could occur on welds and test pieces. This applies to each task being performed such as drilling, cutting or welding.
You undertake that you will not modify, adapt, translate, reverse engineer, decompile, disassemble or create derivative works based on any of the downloaded PDF file, nor will you merge it with any other software or document, even for internal use within your organization.
AS 1554.1 & AS/NZS 1554.1
In this article nzzs is given on the modifications required to previously published Misalignement of plates of equal thickness see Clause 5. Members and components subjected 1545.1 greater outer bend fibre strains shall be assessed using the provisions of Paragraph B4.
A procedure qualification on a single-V butt weld that has been welded from only the one side shall qualify for welding a double-V butt weld and a single-V butt weld that has been welded on both sides. Co py rig Reinforcements shall be removed where welds form part of a faying or contact surface. The diameter of the hole for a plug weld shall be— a b not less 1554.11 the sum of 8 mm plus the thickness of the part containing the hole; and not more than the greater of— i ii the sum of 11 mm plus the thickness of the part containing the hole; and 2.
The intention is that the designer select the category suited to the severity of the service and nominate this on the drawings.
