Discover our leading engineering configurations engineered for high-stability flux-cored wire production. Original equipment with global CE compliance certifications.
In modern manufacturing, AWS A5.20 E71T-1 gas-shielded flux-cored wire serves as the backbone for structural steel fabrication, heavy machinery design, shipbuilding, and pressure vessel manufacturing. Unlike solid wires, which feature uniform cross-sections, drawing E71T-1 requires managing a delicate tube-and-powder profile.
The core challenge of producing E71T-1 cored wire lies in preserving the powder-filling ratio (usually 13% to 17% by weight) across the entire length of the wire spool. Any slight instability in tension, vibration, or reduction ratio during drawing causes powder shifting, core-voids, or outer sheath failures. These irregularities trigger welding defects like porosity, spatter, or mechanical properties mismatch.
Beijing Orient Pengsheng Tech Co., Ltd. addresses these engineering demands by developing specialized, straight-line, non-slip cored wire drawing machines. By reducing mechanical twist, utilizing precision rolling cassettes instead of standard friction dies, and employing closed-loop tension control, our machines preserve the core geometry. This advanced approach delivers consistent arc stability and low diffusible hydrogen in the final weld deposit.
Classification: AWS A5.20 / ASME SFA-5.20
Shielding Gas: 100% CO2 or 75-80% Ar / Balance CO2
Flux Filling Target: 14.5% ± 0.5%
Diameter Range: 1.2mm, 1.4mm, 1.6mm
Key Applications: Marine vessels, heavy earthmovers, infrastructural columns.
By substituting friction dies with rolling cassettes, our machines minimize drawing friction and heat buildup. This design preserves the critical chemical composition of the internal flux core.
Profibus/Profinet communication manages real-time motor speeds across drawing capstans, eliminating sudden tension changes that disrupt powder distribution.
Internal double-channel water cooling prevents thermal stress on the thin sheath of the E71T-1 cored wire, keeping its mechanical properties consistent.
