由冶金部金属制品研究院和钢铁研究总院共同承担的“七五”国家重点科技攻关项目——活化焊丝,于1990年末通过了部级鉴定。活化焊丝用于气体保护焊。它在现有 H08Mn_2Si 钢焊丝内添加焊丝重量3～6%的、由易电离材料为主的多种材料组成的活化剂,改善了 CO_2气体的高导热率和分解时的吸热而
The “Seventh Five-Year Plan” key scientific and technological project jointly activated by the Ministry of Metallurgical Research Institute of Metal Products and China Iron and Steel Research Institute - activated wire passed ministry-level appraisal at the end of 1990. Activated wire for gas shielded welding. It adds 3 ~ 6% of the weight of the wire into the existing H08Mn_2Si steel wire activator composed of a plurality of materials mainly consisting of ionizing materials to improve the high thermal conductivity of CO 2 gas and the endothermic heat of decomposition
