FCAW · Low-alloy steel
E81T1-Ni1
An 80 ksi gas shielded flux cored wire with a nickel addition, used where the finished joint must hold impact toughness at low service temperature.
What the designation means
Point at any character to see what it claims. The classification is a sentence written in fields, not a product name.
- EElectrode carrying the welding current.
- 880,000 psi minimum tensile strength of the deposited weld metal.
- 1All position capability.
- T1A tubular flux cored wire of usability class 1, a gas shielded rutile flux run on direct current electrode positive.
- -Ni1A nickel-bearing deposit at roughly one percent nickel, added to raise low temperature notch toughness.

- Shielding
- A 75 to 80 percent argon blend with the balance carbon dioxide, or 100 percent carbon dioxide depending on the shielding designator on the label
- Minimum tensile
- 80ksi
Typical uses
- Bridge and offshore structures requiring low temperature toughness
- High strength low alloy steel fabrication at the 80 ksi level
- Heavy equipment fabrication under fatigue and impact loading
How it runs
- Smooth spray-like transfer with a fast freezing slag for out of position work
- Nickel addition raises impact toughness in cold service
- Heat input must be controlled to protect the specified impact values
- Full slag coverage and a clean, well washed bead face
Storage and handling
Alloy flux cored wire is moisture sensitive. Keep spools in sealed foil packaging with desiccant and rebag or oven store opened spools.
