摘　　要：提高高纤维素型焊条低温韧性是未能解决好的一大难题。本文分析和研究了各种影响熔敷金属低温韧性的因素,提出了控制熔敷金属化学成分、加入多元合金Ni-Mo-RE微合金化提高低温韧性的新途径,并开发出低温韧性优良的高纤维素型焊条。It is a difficult problem to improve the low tempe rature toughness of high cellulosic electrodes.Factors which affect the low temp erature toughness of deposited metal are analysed and studied in this paper ,and a new method to improve the low temperature toughness is proposed by c ontrolling the chemical compositions in the deposited metal and adding multicomp onent alloy Ni-Mo-RE,and a series of high cellulosic electrodes with high low te mperature toughness are developed.
