A welding procedure specification shall be developed from the PQR, based on the limits of the essential variables of Clause 4. The size of a complete penetration T-joint or corner joint butt weld shall be the thickness of the part that butts against the face of the other part. The flattening of the section shall be made over the minimum length practicable.
To maintain their currency, all Standards are periodically reviewed, and new editions are published. Thursday, 31 March 4: This Standard incorporates Amendment No. Single-run and multi-run fillet welds may be qualified on opposite sides of the same test plates.
Where the structure is not subject to statutory jurisdiction, the principal is deemed to be the inspecting authority.
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 It should then involve a progressive reduction in frequency of testing, on the basis of achieving compliance with each test.
Product Availability See publications the same Subject 2. Fabricators and inspectors should be aware that ultrasonic examinations will not typically detect inclusions normally associated with lamellar tearing e. They reflect the latest scientific and industry experience. Where the manufacturer makes specific recommendations covering conditioning and pretreatment of flux prior to use, such recommendations shall be followed.
In all other cases or where equivalence cannot ass established, it will be necessary to requalify the weld procedure in accordance with the requirements of this Standard. Some consumables may have classifications that vary from that shown.
See Appendix D, Item v.
AS/NZS – Standards Australia
The probe angle shall be the actual measured angle, not the nominal angle. 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.
The size of seal welds shall comply with Clauses 3. 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. Members and components subjected to greater outer bend fibre strains shall be assessed using the provisions of Paragraph B4. structurez
This Standard is limited to the welding of steel parent material with a specified minimum yield strength not exceeding MPa. The width of the slot for slot welds shall be— a not srtuctures than the sum of 8 mm plus the thickness of the part containing the slot; and b not more than the greater of— i the sum of 11 mm plus the thickness of the part containing the slot; and ii 2.
Please copy and paste this embed script to where you structjres to embed Embed Script. All welds shall receive welfing full visual inspection in accordance with Section 6. This Standard does not cover the design of welded connections or permissible stresses in welds, or the production, rectification or repair of castings. If the weld does not comply, the location and extent of the defects shall be given.
Transverse guided bend test Method 5. For system A classified consumables, consumables of the former positional class D are sa to position designation 3 including 4 and P are equivalent to designation 1 including 2 to 5. 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.
In most cases extending the procedure qualification will be particularly if both the trade name and classification of the welding known. This edition incorporates the following major changes to the edition: Where routine testing reveals imperfections requiring further consideration in accordance with Zs 6, Clause 6.
We are a non-profit group that run this strhctures to share documents. The specimen shall comply with the requirements given in Table 4.
Where the weld complies with the relevant test requirements of Clause 4. Where there is a root gap, the size shall be given by the lengths of the legs of the inscribed triangle, reduced by the amount shown in Table E3, Appendix E.
See Appendix D, Items t and u. We need your help to maintenance this website. This Standard does not apply to underwater welding. Where welded joints in these structures are governed by dynamic loading conditions, this Standard applies only to those welded joints that comply with the fatigue provisions of ASAS or NZS Welding power sources IEC T-joints by other portions of the Medium restraint: 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.
The appropriate steel type, suitable for the design service temperature and material thickness, shall be selected in accordance with Paragraphs B4. The centre-to-centre spacing between plug welds shall be not less than four times the diameter of the hole.
When applying these thickness limitations, an adjustment to the minimum preheat temperature may be required see Clause 5. In special cases, metal temperatures cooler than the LODMAT may occur where there is minimum insulation, minimum heat capacity, minimum radiation shielding or abnormally low local temperatures such as snow, ice and frost conditions. See Appendix D, Item a. With the exception of quenched and tempered steels, parent materials not identified to a Standard nominated in Item c above may fo used, provided one of the following requirements is met: It is recommended that the fabricator treat such joints as if they had welving welded with non-prequalified welding consumables.
This Amendment applies to Clauses 2.
Consumables with T grading, no limitation on structurres energy for single-run or two-run technique. In particular, due consideration shall be given to the control of emitted fumes, especially when welding through paints, primers and other surface coatings.
Where matching weathering properties are required, refer to Table 4.
