ER309LSi        符合：YB/T5092 H03Cr24Ni13Si1

不銹鋼焊絲                           相當(dāng)：AWS A5.9 ER309LSi

        ISO 14343-A-G 23 12 L Si

                                     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(dòng)性佳，從而成形更加美觀，送絲順暢、電弧穩(wěn)定、飛濺極少；熔敷金屬的機(jī)械性能穩(wěn)定。因含碳量低，耐腐蝕性能優(yōu)良。

用途：常用于碳鋼與不銹鋼異種材料焊接，石油化工行業(yè)如反映容器內(nèi)壁堆焊過渡金屬，或應(yīng)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-b 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 bl 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 reb vessel in petrochemical industry, or to weld martensite with poor toughness and ferrite stainless steel.

注意事項(xiàng)：

1.      保護(hù)氣體：注意保護(hù)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(shí)除凈。

5.      室外焊接時(shí)，當(dāng)風(fēng)速大于1.5m/s應(yīng)采取適當(dāng)?shù)姆里L(fēng)措施，以防發(fā)生氣孔。

6.      以上建議僅供參考，在具體操作中以現(xiàn)場(chǎng)情況為準(zhǔn)。必要時(shí)先進(jìn)行工藝評(píng)定再確定焊接方案。
