Flux Core Wire : Sorex E71T-1C
Gas-Shielded Flux Cored Wire for Mild Steel (E71T-1C)
Executing high-speed structural carbon steel fabrication across building frameworks, heavy machinery, ship hulls, and storage tanks demands filler metal that delivers continuous high deposition without compromising mechanical integrity. The Gas-Shielded Flux Cored Wire for Mild Steel (E71T-1C) series from Thermatech offers exceptional operational reliability powered by Wire Sorex E71T-1C manufacturing precision.
Classified under AWS A5.20 E71T-1C, Gas-Shielded Flux Cored Wire for Mild Steel (E71T-1C) utilizes a fast-freezing titania slag system that supports stable, all-position welding without puddle sagging or edge undercut. Optimized for use with 100% CO2 shielding gas, this Wire Sorex E71T-1C consumable produces low-hydrogen weld deposits with minimal spatter loss and self-peeling slag. The resulting smooth, aesthetically clean weld beads consistently satisfy stringent non-destructive radiographic (NDT) inspection criteria.
Technical Advantages of Gas-Shielded Flux Cored Wire for Mild Steel (E71T-1C)
Built to maximize throughput and welder efficiency in demanding fabrication shop environments, this product line offers key advantages:
- Superior All-Position Arc Stability: Fast-freezing slag enables effortless vertical-up, vertical-down, and overhead welding with precise puddle control.
- High Travel Speeds & Deposition Efficiency: Wire Sorex E71T-1C flux-cored technology delivers significantly higher deposition rates than standard solid wires, lowering total labor costs per meter of weld.
- Radiographic Quality Deposit: Moisture-resistant formulation ensures low diffusible hydrogen levels, preventing porosity, gas pockets, and cold cracking in thick carbon steel plates.
- Self-Detaching Slag Layer: Slag peels away effortlessly upon cooling, minimizing post-weld grinding and joint preparation time between multi-pass runs.

DESCRIPTION :
- SFC-71 is an all-position rutile flux cored wire designed to be used with CO2 or Ar/CO2 gas mixture.
- It can be used on all-position welds with both single and multiple pass welds for mild steel and low alloy steels.
APPLICATIONS :
- It is widely used for shipbuilding, storage vessels, structural fabrication, machinery and piping,etc.
NOTE ON USAGE :
- Use DC (+) polarity.
- Maintain a higher welding speed in order to get enough penetration in the down hand welding position.
