ISO 14343-A-G 19 9 L
In accordance with:YB/T5092 H03Cr21Ni10Si
Be equivalent to:AWS A5.9 ER308L
ISO 14343-A-G 19 9 L
說明:ER308L焊絲主要成分是低C-18Cr-8Ni。配用SJ601不銹鋼堿性燒結焊劑,其焊縫金屬具有良好的力學性能,抗晶間腐蝕性能、抗裂性良好;具有不增Si、不增C,且Cr、Ni燒損小等特點。
用途:廣泛應用于石油化工等行業(yè),如022Cr19Ni9(SUS304L)等材料的焊接。
Instructions:The ER308L welding stick consists mainly of low C-18Cr-8Ni. It coordinates with the stainless steel alkaline sintered flux SJ601. It’s welding line bl has good mechanical properties and resistance ability to intergranular corrosion and crack. It would not increase Si or C and would burn little Cr and Ni. Due to a low content of carbon, it has excellent inoxidability.
Use:It’s widely used to weld materials in many industries like petrochemical industry, 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
