摘　　要：【目的】针对目前中国新一代核电装备制造对镍基合金堆焊金属性能提出更高的要求,国际通用的690合金ERNiCrFe-7A带极堆焊材料已难以满足350℃高温强度和低DDC(Ductility dip cracking)裂纹敏感性要求。【方法】通过对690合金中各元素作用的分析,确定690合金抗DDC的影响因素。【结果】在690合金ERNiCrFe-13成分基础上,试制了WHDNi693焊带,并成功研制了配套埋弧焊焊剂WSJ693HR,依据所研制的焊接材料,进行了带极堆焊工艺评定试验。【结论】研制的新型镍基合金ERNiCrFe-13带极堆焊材料,堆焊金属力学性能、耐腐蚀性能以及抗DDC性能优良。[Objective]At present,the new generation of nuclear power equipment manufacturing in China puts forward higher requirements for surfacing metal properties of nickel-based alloy,and the internationally used 690 alloy ERNiCrFe-7A surfacing material with electrode has been difficult to meet the requirements of high temperature strength at 350℃and low DDC(Ductility dip cracking)sensitivity.[Methods]Through the analysis of the functions of various elements in 690 alloy,the influence factors of DDC resistance of 690 alloy were determined.[Results]Based on the composition of 690 alloy ERNiCrFe-13,WHDNi693 welding strip was trial-produced,and the matching submerged arc welding flux WSJ693HR was successfully developed.According to the welding materials developed above,the process evaluation experiment of surfacing with electrode was carried out.[Conclusion]The new nickel-based alloy ERNiCrFe-13 surfacing with electrode had excellent mechanical properties,corrosion resistance and DDC resistance.
