摘　　要：对两个厂家的镍基合金焊条ENiCrCoMo-1进行了工艺性和熔敷金属性能对比试验,并对微观形貌进行了分析。试验结果表明,两个厂家的镍基合金焊条ENiCrCoMo-1工艺性能均良好,熔敷金属成分及力学性能均满足国标要求。此外,由于两个厂家镍基合金焊条ENiCrCoMo-1熔敷金属成分的差异,使其凝固树枝晶及析出相形貌和分布不同,从而导致其性能存在一定的差异。The processability and deposited metal properties of ENiCrCoMo-1 nickel base alloy electrode from two manufacturers were compared,and the micro morphology was analyzed.The test results show that the Ni base alloy electrode ENiCrCoMo-1 produced by the two manufacturers has good process performance,and the deposited metal composition and mechanical properties meet the requirements of national standard.In addition,due to the difference in the composition of deposited metal of Ni based alloy electrode ENi Cr Co Mo-1 from two manufacturers,the morphology and distribution of solidified dendrite and precipitated phase are different,which leads to some differences in properties.
