                                     In accordance with：YB/T5092 H03Cr24Ni13Si1

Be equivalent to：AWS A5.9 ER309LSi

ISO 14343-A-G 23 12 L Si

說明：焊絲主要成分是C-23Cr-13Ni，是不銹鋼MIG、TIG焊接材料，可全位置焊接。因添加Si，鐵水流動性佳，從而成形更加美觀，送絲順暢、電弧穩定、飛濺極少；熔敷金屬的機械性能穩定。因含碳量低，耐腐蝕性能優良。

用途：常用于碳鋼與不銹鋼異種材料焊接，石油化工行業如反映容器內壁堆焊過渡金屬，或應用于韌性較差的馬氏體、珠光體不銹鋼焊接。

Instructions：The ER309LSi welding stick consists mainly of C-23Cr-13Ni. 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. Due to a low content of carbon ,it has excellent inoxidability.

Use：It’s usually used to weld carbon steel and stainless dissimilar materials, to resurfacing weld the inner wall of the reaction vessel in petrochemical industry, or to weld martensite with poor toughness and ferrite stainless steel.

注意事項：

1.      保護氣體：注意保護氣體的純度，混合氣配比推薦Ar+1～3%O2。TIG采用純Ar。

2.      氣體流量：20～25L/min。

3.      干伸長度：15～25mm。

4.      將焊接部位的銹層、濕氣、油污、灰塵等確實除凈。

5.      室外焊接時，當風速大于1.5m/s應采取適當的防風措施，以防發生氣孔。

6.      以上建議僅供參考，在具體操作中以現場情況為準。必要時先進行工藝評定再確定焊接方案。
