A titanium type Co2 gas-shielded flux-cored welding wire for low carbon steel and 490MPa high strength steel. It has excellent welding performance, soft and stable arc, lower spatters, good slag detachability and beautiful appearance of weld; suitable for all-position welding. It has high welding efficiency. The weld metal has been given toughening treatment by microelements, so it has excellent low temperature toughness, good crack-resistance, stable and reliable inherent quality.
Used for welding structures made of carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa. Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery etc.
