摘　　要：介绍了一种超低氢型、可进行全位置焊接、强度级别为６００ＭＰａ、低温韧性优良的ＣＯ２气体保护药芯焊丝。分析了药芯成分等因素对焊接飞溅、脱渣、全位置焊接性、烟雾等的影响规律，在大量工艺性能和力学性能试验基础上，设计了焊丝渣系及合金系统，并对焊丝的综合性能进行了全面测试。This paper introduces an ultra - low hydrogen content type flux - cored wire to be used in all position CO2 arc welding with tensile strength of 600 MPa and good low temperature toughness. The influence of flux - core compositions on spat- ter, slag detachability, fume, adaptability of all position welding etc. is analyzed. Based on experiments of usability and mechani- cal properties, the alloying system and slag system of the wire are designed and then the comprehensive tests for the wire are carried cot.
