The ER71T-1C flux-cored welding wire is a self-shielded flux-cored wire designed for high productivity and reliable all-position welding on carbon steel. Its advanced flux formulation enables smooth slag removal, minimal spatter, and excellent bead appearance with deep fusion.
This welding wire is ideal for structural steel fabrication, bridge construction, shipbuilding, and general manufacturing. It supports both single and multi-pass welds with consistent mechanical strength and impact toughness.
