摘　　要： 介绍药芯焊丝的药芯组成及各成分作用,根据药芯配方的降氢机制及合金元素过渡系数,计算出各种药粉理论加入量,结合以前一些试验数据及经验确定了初始配方,再经过多次样品试制及性能检测,设计出合适的药芯配方,试验产品不仅满足GB/T 10045—2001要求,还使熔敷金属中扩散氢质量体积为3.73 m L/100 g,达到了不大于5 m L/100 g的更高要求。 To introduce flux cored composition of flux cored welding wire and role of each composition. All kind of powder theory addition is calculated according to hydrogen reduction mechanism of flux cored formula and alloy element transition coefficient, the initial formula is decided combining with some pervious experimental data and experience, after many times sample trail production and property test, suitable flux cored formula is designed, experimental product meet requirements of GB/T 10045--2001, and diffusion hydrogen quality volume in deposited metal 3.73 mL/100g, reaches higher requirement of no more than 5 mL/100 g.
