摘　　要：对药芯焊丝中各主要组分对其性能的作用和影响进行了研究和探讨。在此基础上研制出一种低氢高韧性全位置用TiO2 -SiO2 -MgO渣系的GL -YJ5 0 2 (Q)药芯焊丝。GL -YJ5 0 2 (Q )药芯焊丝焊接工艺性好 ,扩散氢含量低 。In this paper, the factors affecting the properties of flux-cored wire were studied in detail. A new flux-cored wire GL-YJ502(Q)of TiO 2-SiO 2-MgO slag system with low hydrogen and excellent toughness was developed. GL-YJ502(Q)flux-cored wire provides good usability ,low hydrogen and excellent low temperature notch toughness and has been applied to various fields all over the world.$$$$
