摘 要:由全国焊接标准化技术委员会归口,哈尔滨焊接研究院有限公司负责制修订的GB/T 3670-2021《铜及铜合金焊条》、GB/T 41110-2021《镍及镍合金药芯焊丝》、GB/T 41111-2021《气焊用非合金钢及热强钢填充丝》和GB/T 41112-2021《镁及镁合金焊丝》于2021年12月31日发布,将于2022年7月1日起正式实施。其中《铜及铜合金焊条》为第二次修订,本次修订按照ISO体系转化,重新编制了型号,结构调整大,技术内容变化多。《镍及镍合金药芯焊丝》、《气焊用非合金钢及热强钢填充丝》和《镁及镁合金焊丝》为首次制定,按照ISO相应标准进行转化,主要技术内容与其等同,根据国内使用习惯,在标准结构方面进行了调整,弥补了这三类焊接材料国家标准的空白,为焊材研发、制造、复验提供了重要技术支撑。从型号编制、技术要求对标准制修订情况进行了介绍,并与国外相应的标准进行了比对分析,以便使用者更好地理解、掌握和执行新标准。Directed by the National Welding Standardization Technical Committee,Harbin Welding Institute Limited Com‐pany is responsible for the revision and formulation of GB/T 3670—2021 Covered Electrodes for Manual Metal Arc Weld‐ing of Copper and Copper Alloys,GB/T 41110—2021 Tubular Cored Electrodes for Gas Shielded and Non-gas Shielded Metal Arc Welding of Nickel and Nickel Alloys,GB/T 41111—2021 Rods for Gas Welding of Non-Alloy and Creep-Resisting Steels and GB/T 41112—2021 Solid wire electrodes,solid wires and rods for fusion welding of magnesium and magnesium alloys.These four national standards were issued on December 31,2021 and will be formally implemented on July 1,2022.Covered electrodes for manual metal arc welding of copper and copper alloys is the second revision.This revision has been converted into the ISO system,and the designation has been reformed.The structure has been greatly adjusted,and the tech‐nical content has changed a lot.Tubular cored electrodes for gas shielded and non-gas shielded metal arc welding of nickel and nickel alloys,Rods for gas welding of non-alloy and creep-resisting steels and Solid wire electrodes,solid wires and rods for fusion welding of magnesium and magnesium alloys are formulated.They are converted according to the corre‐sponding ISO standards which the main technical content is the same as.The standard structure has been adjusted according to the domestic usage.These standards make up the blank of the national standard,and provide important technical support for the research and development,manufacturing and re-inspection of welding materials.This paper introduces the revision of the standard system from the designation and technical requirements,and compares and analyzes with the corresponding national standards abroad,so that users can better understand,master and implement the new standards.This paper intro‐duces the situation of revising and formulating the standard,so that users can better understand,master and implement the new standards.Structur
