摘　　要：通过优化焊条熔敷金属中的主要化学成分,提高了3.5%Ni低温钢配套焊条熔敷金属的低温冲击韧性;研制了W107DR低温钢焊条,其熔敷金属的冲击性能达到了进口焊条的实物水平。The low temperature impact toughness of the deposited metal for low-temperature steel with 3.5%Ni was improved by optimizing the main element of deposited metal,and the covered electrode W107DR for low-temperature steel contained Ni was developed,and its toughness is equal to that of the imported electrode.
