NB/T 20002.3-2013 (English Version) PDF

Scope: This part stipulates the requirements that should be met when the nuclear is and machinery and equipment of a pressurized water reactor nuclear power plant evaluates the welding procedure specifications through welding procedure tests, and clarifies the implementation conditions of the welding procedure tests and the effective scope of the welding procedure qualification. This section applies to carbon steel, low alloy steel, austenitic stainless steel, austenitic-ferritic stainless steel and nickel and nickel-based alloys, as well as simulated repair welding, steel casting repair welding, Special welds, austenitic-ferritic stainless steel cladding on carbon steel and low alloy steel, nickel-based alloy cladding on carbon steel and low alloy steel, welding of heat exchanger heat transfer tubes and tube plates Process assessment.
