NB/T 20009.24-2015Welding material for pressurized water reactor nuclear power plants - Part 24: Nickel alloy covered electrodes for safety-related components (English PDF)

NB/T 20009.24-2015 is the English-translated version of 压水堆核电厂用焊接材料 第24部分：安全级设备用镍基合金手工电弧焊焊条.

NB/T 20009.24-2015 addresses nickel alloy covered electrodes inside the Chinese energy industry series on welding consumables for pressurized water reactor nuclear power plants.

It fixes the electrode grades, the technical requirements, the test methods and the inspection rules, as well as packaging, marking and quality documentation. The electrodes concerned are the nickel-base alloy covered electrodes used in manual arc welding on safety class equipment of passive pressurized water reactor plants.

Chemical analysis and testing follow the quoted GB/T 223 and GB/T 8647 series and GB/T 15260-1994, while GB/T 25775, NB/T 20004 and ASTM E 1473 are also listed. Issued on 1 July 2015, it has applied since 1 December 2015.
