E71T-1 1.0/1.2/1.4/1.6mm Flux Cored MIG Welding Wire
Flux Cored Arc Welding Wire (FCAW) AWS A5.20 E71T-1, is 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.
Our advantages is stable arc, little spatter, less smoke; higher deposition efficiency; excellent welding performance; easy restrike.
