AS NZS 2980:2018 pdf free download – Qualification of welders for fusionwelding of steels—Additional requirements for Australia and New Zealand.
A2.2 Terms and definitions
The definitions of examiner’ and ‘examining body’ within AS/NZS Iso 9606.1 (Clause 3) are very broad. To facilitate acceptance of welder certification to this Standard throughout Australia and New Zealand, the examiners should have sufficient technical knowledge and experience to satisfy the examining body of their ability to interpret and apply the requirements of this Standard and the application Standard.
A2.3 Nlinimum qualification requirement for examiners
The recommended minimum qualilicat ion for examiners is as follows:
(a) Visual and destructive tests Examiners assessing test plates and test pieces in accordance with this Standard should hold a formal qualification as a welding supervisor (or higher) or welding inspector. Examples of suitable qualifications are given in AS/NZS 1554 (all parts).
(b) Radiographic and ultrasonic examination Examiners shoti Id hold appropriate qualifications at level 2 or higher issued in accordance with AS ISO 9712.
In certain cases, it may be beneficial to utilize the services of an independent examiner or examining body.
In New Zealand, persons issuing reports on destructive and/or non-destructive examinations may need to be an authorized signatory of an organization accredited by International Accreditation New Zealand (IANZ) to conduct the assessment of tests in accordance with this Standard.
Reference numbers ofselding processes
relding process terminology utilized in Australia and New Zealand varies from that utilized in Europe and subsequently within ISO Standards. The following should be noted:
(a) Gas metal arc welding (GMAW) is separated into its variants within the Standard. Commonly referred to as ‘MIG’ in Australia and New Zealand, the process employing active shielding gases such as argon-based mixed gases and CO2 is referred to as metal active gas welding’ (MAG). The term MIG’ in AS’NZS ISO 9606.1 is reserved specifically for situations where inert shielding gases or gas mixes are utilized.
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 Wcldin 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 to 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 ASJNZS 1554.4. Where required by the specification. other alternatives may he used,
e.g. Category FP of ASINZS 1554.5, AS/NZS 1554.6, etc. Vhere alternative acceptance criteria is utilized, the welder’s certificate should indicate the name of both the test standard. i.e. AS/NZS 2980, and the alternative acceptance criteria.
