Product description

Application: Used for welding structural components of carbon and low alloy steels with tensile strength of 490N/mm², widely applied in shipbuilding, machinery manufacturing, pressure vessels, boilers, petroleum, chemical, lifting machinery, and other structural welding applications. 

Characteristics: E71T-1 is a titania-type flux-cored wire for CO₂ gas shielded welding. The internal flux core ensures excellent welding process performance, increased deposition efficiency, a soft and stable arc, minimal spatter, and aesthetically formed weld seams.
