说明:ER308L焊丝主要成分是低C-18Cr-8Ni。配用SJ601不锈钢碱性烧结焊剂,其焊缝金属具有良好的力学性能,抗晶间腐蚀性能、抗裂性良好;具有不增Si、不增C,且Cr、Ni烧损小等特点。
用途:广泛应用于石油化工等行业,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 metal 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。
