Abstract:

一种低六价铬309奥氏体不锈钢金属芯焊丝及其制备方法属于焊接材料技术领域。该焊丝的钢带为低碳钢钢带,化学成分如下:C:0.03~0.05wt.%;Si:< 0.065wt.%;Mn:< 0.33wt.%;S:< 0.025wt.%;P:< 0.03wt.%。该焊丝药粉的化学组成成分(质量分数wt.%)为:C:0.03~0.065wt.%;Cr:58~63wt.%;Ni:30~33wt.%;Mn:2~3wt.%;Si:0.66~1.5wt.%;Mo:< 0.74wt.%;Ti:0.5~1wt.%;Zn:0.5~1wt.%;Zr:0.5~1 wt.%;Fe:余量。本发明在焊接烟尘量稍低的条件下,其中有毒Cr(VI)排放量与同类型实芯焊丝相比可降低21~27%。本发明采用低碳钢钢带,因此该焊丝成本可大大降低,该焊丝焊接电弧稳定,飞溅小,焊缝成形美观,熔敷金属综合性能优良。
