| Product Model:ER70S-6 |
| Description: |
| ER70S-6 is a kind of mild steel copper coated welding wire, suitable for 100% CO2 and Argon& CO2 mixed gas protective welding with stable feasibility, good welding seams, less spatters and excellent welding process properties. |
| Application: |
| Used to weld ship building steel(A,B,D,E,A36,D36,E36)and equivalent mild steel or 550Mpa grade mild alloy steel, such as container building, construction machine, railway construction, pressure vessel for semi-auto or automatic gas shielded welding. |
