To maintain the
8、ir currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been
9、 published since the Standard was purchased.Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Australia web site at .au or Standards New Zealand web site at www.standard.co.nz and looking up the relevant Standard in the on-line catalogue.Alterna

For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these

16、zing qualification.This Standard incorporates Amendment No. 1 (April 2000). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure, or part thereof affected.This Standard is the result of a consensus among repres
17、entative on the Joint Committee to produce it as a Joint Australian/New Zealand Standard. Consensus means general agreement by all interested parties. Consensus includes an attempt to remove all objections and implies much more than the concept of a simple majority, but not necessarily unanimity. It
18、 is consistent with this meaning that a member may be included in the Committee list and yet not be in full agreement will all clauses of this Standard.This Standard unifies and revises the requirements for the qualification of welding and brazing procedures, welding and brazing personnel, and produ
19、ction test plates and welds, specified in AS 1210, Pressure vessels, AS 1228, Pressure equipment Boilers and AS 4041, Pressure piping.The main changes in this revision are as follows:(a) Inclusion of Amendments 1 and 2 to AS 3992 1992.(b) Inclusion of requirements for hard facing metal overlay. (c)
20、Publication as a Joint Australian/New Zealand Standard.(d) Clarification and revision of text to current accepted welding and brazing practice. (e) Addition of diagrams to define parent material thickness.(f) Recognition of the changing role of the Australian regulatory authorities.The objective of
21、this Standard is to reduce misunderstanding, costs and delays in qualifying welding; avoid unnecessary duplication of testing; promote greater confidence in reciprocal acceptance of approved procedures; and improve safety.This Standard is based on AS 1210, with due allowance for practices or require
22、ments of AS 1228 and AS 4041. Modifications have been made to utilize current appropriate requirements of ASME BPV Sec IX ASME Boiler and Pressure Vessel Code, Section IX: Qualification standard for welding, brazing procedures, welders, brazers and welding and brazing operators, ISO 9956, Specificat
23、ion and approval of welding procedures for metallic materials, BS EN 287, Approval testing of welders for fusion welding, Part 1: Steels, BS EN 288, Specification and approval of welding proceedings for metallic materials, Part 1: General rules for fusion welding and AS 2885, Pipelines Gas and liqui
24、d petroleum, Part 2: Welding.Requirements have been formulated with a view to maximum compatibility with recognized leading international Standards.This Standard introduced to the Pressure Equipment Standards the concept of prequalified welding procedures, i.e. procedures which have been proved by e
25、xtensive use by many organizations to meet the quality requirements of the Standards readily and consistently. Such procedures are limited to materials and thicknesses which are readily welded with proved processes and consumables by qualified welders.It is not intended that the publication of this
26、edition will invalidate welding tests that were accepted in respect of other Standards of AS/NZS 1200, Pressure equipment.Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard.The Standard is downloaded from Standard SharingAccessedbyU
