ER308LSi 符合:YB/T5092 H03Cr21Ni10Si1
不銹鋼焊絲 相當:AWS A5.9 ER308LSi
ISO 14343-A-G 19 9 L Si
In accordance with:YB/T5092 H03Cr21Ni10Si1
Be equivalent to:AWS A5.9 ER308LSi
ISO 14343-A-G 19 9 L Si
說明:焊絲主要成分是C-18Cr-8Ni,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(wěn)定、飛濺極少;熔敷金屬的機械性能穩(wěn)定。
用途:廣泛應用于石油化工、壓力容器、食品機械、醫(yī)療器械、化肥等相關產(chǎn)業(yè),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-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.
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?shù)姆里L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)場情況為準。必要時先進行工藝評定再確定焊接方案。
