AS/NZS 1554.1:2014 A1 Structural steel welding – Part 1: Welding of steel structures: Amendment 1

Free shrinkage restricted structure e. V-notch impact test is required for heat-affected zone Where practicable, it is recommended that the principal resolve any problems with the fabricator, before work is commenced.

Where routine testing reveals stteel requiring further consideration in accordance with Section 6, Clause 6.

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 In welds made from two sides, specimens shall be taken from the first welded side.

Joint details that minimize stress intensity on parent materials subject to stress in the through-thickness direction shall be used where practical.

Care should be taken in applying this Table to imported steels as verification tests may be required. Table B1 may be used without modification for welded members and connection components that are not subjected to more than 1. See Appendix D, Item k. Typical joint preparations for connections butt-welded from one side are shown in Figure 4.

T-joints by other portions of the Medium restraint: 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: For MMAW consumables, the welsing 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.


This strain arises from the shrinkage of the weld metal as it cools.

This is largely due to the ISO based classifications for most processes adopting similar strength, impact resistance and hydrogen control designations. Welding power sources IEC For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options.

On the completion of the test, the dimension of any crack or other defect in the weld or the heat-affected zone shall be not greater than 3 mm, measured in any direction at the outer surface of the test specimen. This Standard requires that weld preparations, welding consumables and welding procedures be qualified before commencement of welding. The inspector shall have the opportunity to witness all testing of welding procedures and welder qualification tests that are required.

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.

The fabricator shall establish a welding procedure and 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.

Parent metal discontinuities which interfere with the examination should be reported to the principal and included in the test report.

Where a slot weld is made by completely or partially filling the slot i. Licence Agreement Legislation; 3. Product Availability See publications the same Subject 2.

Such variations include transducer sizes and frequencies. Specifying weld sizes larger than necessary shall be avoided. 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 See Appendix D, Item a. Variations to the equipment requirements may be used upon agreement with the principal.

The ultrasonic sensitivity to be used for parent metal scanning in areas where welds are to be made should comply with ASi. Charpy V-notch impact fracture toughness test Non-destructive testing—Ultrasonic testing of fusion welded joints in carbon and low alloy steel Certification of welding supervisors—Structural steel welding Radiography of metals—Image recommendations for their use Resistance welding equipment—Single-phase a.


The centre-to-centre spacing between plug welds shall be not less than four times the diameter of the hole.

This Standard does not apply to underwater welding. Where this is not possible, additional gain shall be added in accordance with Table 6. Strutures strain due to weld distortion should be disregarded. Any steel type from any of the above Standards may be welded to any other steel type from any Standard listed above, provided the requirements of this Standard are met for each of the steels.

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. Hardness tests for the qualification of procedures employing consumables not prequalified shall show that the weld metal does not exceed the parent metal hardness by more than HV These standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate.

When applying this qualification 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.

A change in the pulse parameters includes a change in pulse waveform [Item q of Table 4.

TM gradingno limitation on arc energy for single-run or multi-run technique. See Appendix D, Items tx and y.

A welding procedure specification shall be developed from the PQR, based on the limits of the essential variables of Clause 4. 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 temperature see Paragraph B3, Appendix B.
