ER70S-6 mild steel MIG (GMAW) alloy is a general purpose welding alloy for fabrication of mild steel. It contains more deoxidizers than ER70S-3. The additional deoxidizers also provide better wetting, giving a flatter bead shape and the capability of faster travel speeds. Usually used with 75/25 (argon/carbon dioxide) shielding gas or with higher contents of argon, such as 90/10. It can also be used with 100% carbon dioxide.
Features
- General-purpose MIG (GMAW) welding wire for fabrication of mild steel
- Contains the highest combination of silicon and manganese as deoxidizers
- The deoxidizers provide better wetting, giving a flatter bead shape and the capability of faster travel speeds
- Permits high current welding with 100% carbon dioxide shielding gas or 75% argon/25% carbon dioxide shielding gas
- Good out-of-position welding using short circuiting transfer
- Primarily used for multiple pass on steels where rusty and dirty surfaces are not cleaned before welding
- Conforms to AISI/AWS A5.18 ER70S-6
Typical Applications
- Multiple pass on steels where rusty and dirty surfaces are not cleaned before welding.
