NB/T 20009.22-2015Welding material for pressurized water reactor nuclear power plants - Part 22: Low alloy covered electrodes for safety-related components (English PDF)

NB/T 20009.22-2015 is the English-translated version of 压水堆核电厂用焊接材料 第22部分：安全级设备用低合金钢手工电弧焊焊条.

Part 22 of the NB/T 20009 series, NB/T 20009.22-2015, covers the low alloy covered electrodes used on safety-related components of pressurized water reactor nuclear power plants.

It fixes the electrode models for shielded metal arc welding of low alloy steel in such equipment, together with the technical requirements, the test methods, the inspection rules, the packaging and marking and the quality certification documents that accompany them.

It applies to the manual arc welding of low alloy steel in the safety-class equipment of passive pressurized water reactor plants. Its chemical and mechanical testing leans on the parts of GB/T 223, on GB/T 5117, GB/T 25774.1-2010, GB/T 25778-2010, NB/T 20004-2014, NB/T 20328.3-2015 and AWS A4.4M. Issued on 1 July 2015, it has applied since 1 December 2015.
