GB/T 9460-2008Copper and copper alloy wires and rods (English PDF)

Foreword

The revision of this standard adopts ISO/DIS 24373.2007 "Welding

consumables - Solid wires and rods for fusion welding of copper and copper

alloys - Classification" (English version).

This standard was re-drafted in accordance with ISO/DIS 24373.2007.

Considering the actual situation of copper and copper alloy wires and rods in

China, the following technical content modifications have been made to

ISO/DIS 24373.2007.

- DELETE the normative references ISO 544, ISO 4063, ISO 14344, ISO 31-

0.1992;

- ADD Appendix A and Appendix B, brief description of welding wire and

comparison table of main international standard models;

- ADD Tables 2, 3, 4, Figure 1.

For ease of use, this standard also makes the following editorial changes.

- CHANGE the standard name to "Copper and copper alloy wires and rods";

- In terms of standard structure, ADD the inspection rules, markings, quality

certificates;

- CHANGE "this international standard" into "this standard";

- USE the decimal point "." to replace comma "," which functions as a decimal

point;

- DELETE the foreword of international standard.

This standard is a revision of GB/T 9460-1988 "Welding wire and rods of copper

and copper alloys". Compared with GB/T 9460-1988, the main revisions are as

follows.

- The method of classification of welding wire and model division adopts

ISO/DIS 24373.2007;

- The chemical composition of the welding wire is consistent with the

requirements of ISO/DIS 24373.2007; add 18 models of welding wire;

- ADD the warpage and relaxation diameter requirements of welding wire;

- MAKE adjustment of the size of welding wire and packaging method

accordingly in accordance with the requirements of ISO/DIS 24373.2007;

Copper and copper alloy wires and rods

1 Scope

This standard specifies the classification and model, technical requirements,

test methods, inspection rules, packaging, marking and quality certificate of
