Frequently Asked Questions
What is E71T-11 welding wire?
E71T-11 is a gasless, self-shielding flux-cored wire designed for all-position welding of thin mild and galvanized steel. It provides a smooth arc and excellent slag removal.
Does E71T-11 require CO2 gas shielding?
While many flux-cored wires require external gas, E71T-11 is typically self-shielded; however, the TI type specified in the description is optimized for CO2 welding to ensure high cladding efficiency and better technical performance.
What are the main applications for this wire?
It is widely used for welding ships, pressure vessels, machinery, and structural steel components where high anti-porosity and strong weld joints are required.
Can it be used for multi-layer welding?
Yes, it can continuously weld up to three layers before cleaning slag, which significantly improves work efficiency in flat and horizontal fillet welding.
What are the mechanical advantages of deposited metal?
The deposited metal offers a yield strength of 480 MPa and a tensile strength of 530 MPa, with excellent impact toughness even at temperatures as low as -20°C.
Is this wire suitable for all welding positions?
Yes, it is designed for all-position welding including PA (Flat), PB (Horizontal-vertical), PC (Horizontal), and other complex positions like vertical up and overhead.
