摘　　要：研制的Ti-B微合金化CO_2气体保护焊HS-50T实芯焊丝的熔敷金属力学性能完全满足美国ER70S-6的技术要求.其低温韧性与国外同类优质焊丝相当,并且具有合适的抗拉强度.HS-50T焊丝焊接工艺性能良好,适合于全位置焊接.HS-50T CMAW electrode wire microalloyed with Ti-B possesses weld metal strength up to 500MPa which fulfills ER70S-6 criterion. The bw temperature toughness of the wire matches any similar one abroad. It works well for positional different welding and is better than H08Mn2SiA wire currently used for its whole properties.
