摘要
反应堆压力容器用材料主要是Mn-Mo-Ni钢,其压力边界焊缝使用的焊接方法仅为焊条电弧焊(SMAW)、埋弧焊(SAW)。为了提高焊接质量、减少清根的工作量,进行了反应堆压力容器Mn-Mo-Ni(SA-508 Gr.3 Cl.1)配套钨极惰性气体保护焊(GTAW)工艺的研究,并完成了焊接工艺评定试验。研究结果表明,钨极惰性气体保护焊可用于反应堆压力容器产品焊接。
Reactor pressure vessel material is mainly Mn-Mo-Ni steel,the present welding processes for pressure boundary weld are only shielding metal arc welding(SMAW)and submerged arc welding(SAW).In order to improve welding quality and back-gouging work,gas tungsten arc welding(GTAW)process for Mn-Mo-Ni(SA-508 Gr.3Cl.1)of reactor pressure vessel was developed,and welding procedure qualification test was completed successfully.The results show that the tungsten arc welding(GTAW)welding process can be used on production weld of reactor pressure vessel.
