AS NZS 2980:2018 pdf free download – Qualification of welders for fusion welding of steels-Additional requirements for Australia and New Zealand
A2.5 Filler material grouping
Most of the ISO consumable classification Standards provided as examples in AS/NZS ISO 9606.1 (Table 2) have been adopted in Australia and New Zealand. See Clause 3.3 for Australian or Australian/New Zealand Standards that may be used as alternatives to these ISO Standards for the application of this Standard.
A2.6 Test pieces
The test piece lengths (see AS/NZS ISO 9606.1, Clause 6.2) are suitable for most welding processes; however, users should note that longer test pieces may be required where the weld procedure is being qualified as part of the welder’ s qualification test process, particularly where additional tests not listed within this Standard may be required. For high speed or higher amperage welding processes, longer test pieces may be required to ensure adequate crater fill, e.g. SAW.
A2.7 Welding conditions (Section 6.3)
The qualification test of welders should follow weld procedure documents (pWPS or WPS) prepared in accordance with the application Standard or AS/NZS 1554.1 unless otherwise specified. All pWPS or WPS documents should report the material group number (see ISO/TR 15608 and Appendix D of this Standard) of parent materials.
A2.8 Test methods
Test methods should follow those specified in the application Standards or Appendix B unless otherwise specified. The methods are similar t those listed within AS/NZS ISO 9606.1 Clause 6.4 or provide an equivalent technical outcome.
A2.9 Acceptance
AS/NZS ISO 9606.1 (Clause 7) provides for the use of alternative acceptance criteria for imperfections. Two alternative criteria are provided for in the Appendices of this Standard and are identical to that published in the superseded AS/NZS 2980. Appendix B conforms to the requirements of a number of Standards including category SP of AS/NZS 1554.1 and AS/NZS 1554.4. Where required by the specification, other alternatives may be used, e.g. Category FP of AS/NZS 1554.5, AS/NZS 1554.6, etc.
A2.10 Revalidation
Revalidation (AS/NZS ISO 9606.1 Clause 9.3) was referred to as Prolongation in AS/NZS 2980 and previous editions of ISO 9606-1. A variety of methods are now available to extend the period of qualification. Welders who change employment during the life of their certificate may be able to obtain ongoing confirmation and validation with their new employer provided that the requirements of Clauses 9.2 and 9.3 are met.
