Foreword

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

This standard uses the redrafting method to amend and adopt ISO 15614-6.2006 "Metal Material Welding Procedure Specification and Qualified Welding Procedure Evaluation"

Fixed test part 6.arc welding of copper and copper alloys".

Compared with ISO 15614-6.2006, this standard has technical differences, and the clauses involved in these differences have been passed on the outer margins.

The vertical single line (|) of the position is marked, and Appendix A gives a list of the corresponding technical differences and their reasons.

This standard also made the following editorial changes.

---Modified the standard name;

---Revised references.

This standard was proposed and managed by the National Welding Standardization Technical Committee (SAC/TC55).
