摘　　要：保持药芯中合金成分不变,改变药芯填料不同组分的含量,在相同的焊接条件下,观察了药芯组分含量变化对焊接工艺性能的影响。试验表明:在钛钙型药芯焊丝中,金红石:氟化物: (石英+钾长石) =1: 2: 9,铝镁合金和其它元素含量合适时,自保护药芯焊丝的焊接工艺性能和力学性能良好,具有广泛的应用前景。Effects of the change of chemical content on welding processing property is observed in the same welding condition by changing the content of different element in the flux core. The results show that when the content rate of TiO 2 /CaF 2 /SiO 2 is 1/2/ 9,the content of Al-Mg alloy and the content of other elements are suitable, the self-shielded flux cored wire has good welding processing property and mechanical property, which make the wires have a wide application.
