CO2
gas-shielded welding wire
CO2 gas-shielded welding wires (Type ER70S-6,ER70S-G,ER49-1)are
primarily used for all position welding of steel structures,
pressure vessels, containers, constructions machinery,
ships, railways, automobiles, motorcyclesand 300MW thermoelectric
generators and are characterized by excellent welding
performance and mechanical Performance, stable electric
arc, few splattering, good welding seam forming and
high deposition efficiency.
