| 摘 要： | 测试了市售的3种不同厂家的药芯焊丝的发尘率，研究了铁粉添加量对焊丝发尘率的彭响。并对烟尘进行了等离子电感耦合光谱分析和X射线衍射物相分析。研究结果表明：烟尘中铁的氧化物约占50％。当药芯焊丝中的w(Fe)=19．5％-28．7％时，焊丝发尘量为5．5226-8．2326g／kg；实验条件下铁粉在药芯中所占比例越小，单位质量的焊丝发尘量就越少；不同厂家、不同工艺生产的铁粉时发尘量没有明显的影响。

| Abstract: | The fume formation rate of flux-cored wire produced by three different manufacturers is investigated,the effect of the content of iron powder on the FFR is also studied,and the fume is analyzed by the Inductively-coupled Plasma(ICP) and X-ray.The result shows that 50% of the fume is iron oxide,and the FFR vary from 5.522 6 g/kg to 8.232 6 g/kg when the content of iron powder vary from 19.5% to 28.7%.The FFR declined along with the decrease of iron powder content,and no obvious effects of iron powder produced on the FFR by different manufacturers and different process. |
