摘要

国产核电堆型“华龙一号”反应堆压力容器采用低合金钢16MND5，对其配套焊条完成了国产化研制。焊条的焊接工艺长期以来依赖焊工经验，难以科学、定量地判定焊条焊接工艺性能的优劣，通过对工艺性能指标定量化评价方法的研究，对新研国产焊条和进口焊条进行了工艺性能量化评测对比，归纳研究影响焊接工艺稳定性的因素，如电弧稳定性、脱渣性、成形外观等，以定量的方法对焊接材料工艺性能指标进行科学评价。从评价结果来看，现有的工艺性能量化评价标准方法可以对焊条焊接工艺性能进行科学的评估，对比评价结果，国产手工电焊条在工艺性能方面与进口焊材相当。通过量化评估，证明了国产焊材实现了从“能用”到“好用”的转变。

Abstract

Low alloy steel 16MND5 for pressure vessel of domestic nuclear power reactor type "HPR1000" reactor has been developed domestically with manual welding electrode. Electrode welding process has long relied on the experience of welding workers

and it is difficult to scientifically and quantitatively determine the advantages and disadvantages of electrode welding process performance. Through the research on the quantitative evaluation method of process performance index

the comparison and quantitative evaluation of process performance between newly developed domestic electrodes and imported welding materials are carried out

and the factors affecting the stability of welding process are summarized and studied

such as arc stability For slag removal and forming appearance

the process performance indexes of welding materials are scientifically evaluated by quantitative method. From the evaluation results

the existing quantitative evaluation standards and methods of process performance can scientifically evaluate the welding process performance of welding electrodes. Compared with the evaluation results

the process performance of domestic manual welding electrodes is equivalent to that of imported welding materials

reaching the research goal of the subject project. Through quantitative evaluation

it is proved that domestic welding materials have realized the transformation from "usable" to "easy to use".
