摘要

焊接工艺评定目的是确定焊接工艺过程特性、金属特性及工艺有效范围的工艺参数

验证所得到的焊接接头是否满足标准要求。通过国内首堆"华龙一号"核电站核岛管道、设备安装所需焊接工艺评定标准《压水堆核电厂机械设备焊接规范》与M310堆型核电站焊接工艺评定标准由"RCC-M标准第IV卷S篇焊接"的实际应用

从焊接工艺规范中的焊接工艺通用要求、焊接工艺要素覆盖规则等方面进行分析

为工程技术人员在使用标准时提供一定的参考。

Abstract

The welding process qualification is mainly to determine the welding process characteristics

metal characteristics and process have a valid range of process parameters

to verify whether the obtained welded joints meet the standard requirements. The welding procedure qualification standard for the installation of nuclear island pipelines and equipment for the first pile of Hualong No. 1 nuclear power plant in China

the welding specification for mechanical equipment of pressurized water reactor nuclear power plant and the welding procedure qualification standard for M310 reactor nuclear power plant are "RCC-M Standard Volume IV S The practical application of "welding"

this article analyzes the general requirements of the welding process specification and the welding process element covering rules

etc.

for the engineering technicians in the standard Give certain insights when using.
