GB/T 32257-2015Qualification testing of welders for fusion welding on nickel and nickel alloys (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses redrafted Law Amendment uses ISO 9606-4:1999 "welders - Fusion welding - Part 4. Nickel and nickel alloys." this standard and ISO 9606-4:1999 and its main technical difference between the following reasons.

--- Increasing the recommended format welder qualification certificates, welders approval mark, certificate extension to be confirmed and the content of nickel and nickel alloys Classification guidelines, and give in order to operate in the form of appendices;

--- Unified regulations of the main parameters of welders and the scope of accreditation, and the recognition of the scope of the base metal and welding position were necessary adjustments Whole, making it more clear, specific, reasonable, easy to use;

--- The ISO 9606-4:1999 foreign standards referenced in accordance with the actual situation of our country have been adjusted. Terminology, definitions, Welding Technology Procedures, non-destructive inspection and destructive testing methods - Part of the appropriate standards in place to facilitate the implementation.

This standard made the following editorial changes.

--- Added Appendix A (informative) "welder qualification certificate";

--- Added Appendix B (informative) "welders approval mark Example";

--- Added Appendix C (informative) "professional knowledge";

--- Added Appendix D (informative) "deferred to be confirmed and traceable parameters';

--- Added Appendix E (normative) "Nickel and nickel alloys Classification Guide." this standard by the National Standardization Technical Committee welded (SAC/TC55) and focal points.
