The fabricator shall establish a welding procedure strkctures list the applicable parameters in the welding procedure qualification record also known as PQR or WPQRwhich shall be held as a record and shall be available for examination. Where the consumable used to qualify a weld procedure has been identified on the weld procedure using its trade name and classification, the fabricator should append a note on the original procedure qualification record PQR noting the change of classification for the welding consumable.
For plate thicknesses of less than 15 mm, the transducer size may be reduced to 8 mm and frequencies increased to 5 MHz. This role is vital in assisting local industry to compete in international markets. See Appendix D, Item j. See Appendix D, Items g and h.
AS/NZS 1554.1:2014 A1 Structural steel welding – Part 1: Welding of steel structures: Amendment 1
Published on 23 September The minimum spacing of lines of slot welds in a direction transverse to their length shall be four times the width of the slot. Free shrinkage restricted structure e.
Care should be taken in applying this Table to imported steels as verification tests may be required. Where a change in an essential variable for a welding procedure exceeds the relevant limits given in Table 4.

Welded I sections Pressure equipment—Welding and brazing qualification Cold-formed steel structures Welding consumables—Covered electrodes for manual metal arc welding of non-alloy and fine grain steels—Classification Welding consumables—Covered electrodes for manual metal arc welding of high-strength steels—Classification Welding consumables—Wire electrodes and weld deposits for gas shielded metal arc welding of non alloy and fine grain steels—Classification ISO Low and intermediate alloy steel electrodes for manual metal-arc welding of carbon steels and low and intermediate alloy steels superseded Should discontinuities be later detected in the weld heat affected zone it should be remembered that imperfections of parent metal origin are not considered a cause for rejection of the weld see Clause 6.
Size px x x x x The depth of the filling of plug welds shall be strructures set out in Table 3. In addition, the impact test temperature of the consumables as specified in the relevant Standard for the consumables shall not be warmer than the design service struvtures see Paragraph B3, Appendix B.
Examples include but are not limited to a change from V-shape to U-shape, a change from V-shape to bevel-shape. Premature failure at the corners of the test specimen shall not be considered cause for rejection.
T-joints by other portions of the Medium restraint: This Amendment applies to Clauses 2.
Weld joint hardness test Method 7. See Appendix D, Item b. See Appendix D, Item d.
This Standard requires that weld preparations, welding consumables and welding procedures be qualified before commencement of welding. For the purposes of Table 6. Filler metal for welding Recommended practices for occupational eye protection Personal eye protection series Any qs type from any of the above Standards may be welded to any other steel type from any Standard listed above, structurees the requirements of this Standard are met for each of the steels.
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. This strain arises from the shrinkage of the weld metal as it cools. Hardness tests for the qualification of procedures employing strudtures not prequalified shall show that the weld metal does not exceed the parent metal hardness by more than HV Variations to the equipment requirements may be used upon agreement with the principal.
The specimen shall comply with the requirements of Clauses 5. The Standards Council of New Strudtures is the national authority responsible for the production of Standards.
Control of lamellar tearing Technical Note 7: Where routine testing reveals imperfections requiring further consideration in accordance with Section 6, Clause 6. For additional requirements for hollow sections, see Clause 4.
Where such penetration is achieved, the size of the weld may be correspondingly reduced.
For MMAW consumables, the situation is more 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. 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.
