Be equivalent to：AWS A5.9 ER308LSi

ISO 14343-A-G 19 9 L Si

说明：焊丝主要成分是C-18Cr-8Ni，是不锈钢MIG、TIG焊接材料，可全位置焊接。因添加Si，铁水流动性佳，从而成形更加美观，送丝顺畅、电弧稳定、飞溅极少；熔敷金属的机械性能稳定。

用途：广泛应用于石油化工、压力容器、食品机械、医疗器械、化肥等相关产业，如022Cr19Ni9（SUS304L）等材料的焊接。

Instructions：The ER308LSi welding stick consists mainly of C-18Cr-8Ni. It belongs to stainless steel MIG and TIG welding material and can be used to all-position welding. Because of the addition of Si, the molten iron flows well as to shape up more beautifully and to feed wire more smoothly, with sable voltaic arc and little splatter. The deposited metal has steady mechanical property.

Use:  It’s widely used to weld materials in petrochemical industry, pressure vessels, food machinery, medical equipment, fertilizer and other related industries, such as 022Cr19Ni9（SUS304L）.

注意事项：

1.      保护气体：注意保护气体的纯度，混合气配比推荐Ar+1～3%O2。TIG采用纯Ar。

2.      气体流量：20～25L/min。

3.      干伸长度：15～25mm。

4.      将焊接部位的锈层、湿气、油污、灰尘等确实除净。

5.      室外焊接时，当风速大于1.5m/s应采取适当的防风措施，以防发生气孔。

6.      以上建议仅供参考，在具体操作中以现场情况为准。必要时先进行工艺评定再确定焊接方案。
