AS NZS 2980:2018 pdf free.Qualification of welders for fusion welding of steels
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.
The recommended minimum qualification 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 should hold appropriate qualifications at level 2 or higher issued in accordance with AS ISO 9712.
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Two alternative criteria are provided for in the Appendices of this Standard and are identical to that published in the superseded AS/NZS 2980.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. Where 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.
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.
As the optional job knowledge syllabus provided within Annex B is similar to the competency requirements for the AS 1796 theory exams, welders who have successfully passed their AS 1796 Paper A and Paper B theory exams are able claim a job knowledge designation of ‘Accepted’ on their welders certificate (AS/NZS ISO 9606.1 Section 10).AS NZS 2980 pdf free download.
