Product Description

Product Description

E71T-1C Flux-Cored Welding WireE71T-1C is a titania-type slag system, CO₂ gas-shielded flux-cored welding wire, classified under AWS A5.20 E71T-1C, GB/T 10045 T492T1-1C1A, and EN ISO 17632-B-T492T1-1CA. It is specifically designed for welding 490 MPa high-strength steel structures across demanding industrial applications.This welding wire delivers excellent process characteristics, including a stable arc, minimal spatter, easy slag removal, and a smooth, attractive weld bead appearance. One of its key advantages is outstanding all-position welding capability, including vertical down welding, which significantly improves fabrication efficiency. These features make E71T-1C particularly suitable for shipbuilding, mechanical manufacturing, container fabrication, petrochemical engineering, bridge construction, and other structural steel applications.The deposited metal exhibits sound mechanical properties that meet or exceed standard requirements. Typical values include a tensile strength of 560 MPa (standard: 490–670 MPa), yield strength of 480 MPa (≥390 MPa), elongation of 27% (≥18%), and exceptional Charpy V-notch impact toughness of 120 J at -20°C (≥27 J), ensuring reliable performance even in low-temperature service conditions.For optimal results, use DC reverse polarity with 100% CO₂ shielding gas at a flow rate of 15–25 L/min. Protect the welding zone from wind to prevent air intrusion. Thoroughly remove rust, oil, moisture, and scale from the groove and surrounding area before welding. Store the wire in a dry condition and never use damp wire. Maintain proper wire stick-out, clean slag completely after each pass for multi-pass welding, and match appropriate current and voltage to avoid defects. For thick plates or low-temperature welding, proper preheating is recommended.
