GB/T 39279-2020Wire electrodes, wires, rods and deposits for gas shielded arc welding of creep-resisting steels (English PDF)

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 21952.2012 "Welding Materials Classification for Hot Steel Gas Shielded Arc Welding Wire and Deposited Metal".

Compared with ISO 21952.2012, this standard has many adjustments in structure. Appendix A lists this standard and ISO 21952.2012

A list of changes in chapter numbers.

Compared with ISO 21952.2012, this standard has technical differences. Appendix B gives a list of corresponding technical differences and their reasons.

This standard also made the following editorial changes.

--- Modify the standard name to "Heat Strength Steel Solid Wire for Gas Shielded Arc Welding";

---Added Appendix C (informative appendix) welding wire model comparison.

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