Abstract

Abstract

This paper studies the differences on structure and content of the welding procedure qualification standard NB/T 20002 and ASME-Ⅸ for the G-three nuclear power station ACP1000 and AP1000. This paper selects butt-welding with Shielded Metal Arc Welding（SMAW）, which is the most widely used welding process, analyzes the differences between NB/T 20002 and ASME-Ⅸ, and makes a comparison study on testing and acceptance level of welding procedure qualification, and finally gives a evaluation conclusion.
- ASME-Ⅸ,
- NB/T 20002.3,
- Welding procedure qualification
