Copper coated steel welding wire ER70S-6
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.

Matters needing attention:
1.Wire into the plant must be stored in dry conditions, can not
open wire reel waterproof package.
2.Welding shall be removed before welding surface oil, rust,water
and other impurities.
3.The CO2 gas protection, CO2gas purity 99.98%.
4.CO2 welding protective gas flow rate should be controlled at
20~25L/min.
5.Wire extension length should be controlled in the range of
15~25mm.
6.Preheatig before welding to weld 150℃~300℃, 700℃~740℃ tempering
treatment only after.
