ER70S-6 Gas Shielded Welding Wire 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.
When welding, the welding wire has fast melting speed, stable arc, less welding spatter, beautiful weld bead formation, strong anti-oxidation and corrosion resistance, low sensitivity of cladding metal pores, and good all-position welding process.
Uses: used in large-scale hydraulic steel structures, ships, power stations, boilers and pressure vessels, petrochemicals.

TIG Welding Wire Copper Coated

● The carbon steel and low carbon steel welding wire used for the gas-shielded arc welding is characterized with the excellent welding performance.

● The wire feeding will be stable, and the welding seam will be formed beautifully.

● Moreover, the welding smoke and splash will be relatively moderate, the liquidity and crack resistance will be rather superior.

● The welding deslag will be thin and easy to be peeled off, at the meantime, the welding seam holds high tensile strength and excellent low-temperature impact resistance performance.

● Besides, it is applicable to the all-position( F, H, OH, V ) welding and a larger welding current range.
