Tru-Core® FC 81T-Ni1 is a low alloy steel electrode for gas shielded, flux cored arc welding of those carbon and low alloy steels requiring a minimum tensile strength of 80 ksi and good CVN values at temperatures of -40°F and lower. This electrode is intended for welding in all positions, both single and multiple pass welds, using a shielding gas of 100% Carbon Dioxide. The arc transfer is a smooth, small droplet mode, with very little spatter residue. The slag freezes quickly enough to facilitate welding in all positions, but provides the type of flow and wetting properties to allow good bead geometry and tie in, even in horizontal fillets.
CHARACTERISTICS
Excellent mechanical properties
Fast-freezing slag system
Good bead geometry
Smooth arc transfer
Good low-temperature CVN properties
Excellent feedability
Better sidewall fusion than solid electrodes
APPLICATIONS
Tru-Core® FC 81T-Ni1 is well suited to those applications where any combination of all position welding, good welder appeal, a minimum tensile strength of 80 ksi, good CVN values at lower temperatures.
Some examples are:
Offshore oil structures
Subsea components of oil and gas systems
Earthmoving equipment
Mining machinery
Power generation equipment
Shipbuilding
TYPICAL APPLICATION SHIELDING GAS BLENDS
100% CO2
Flow Rate: 35-45 CFH
WELDING POSITIONS
All position welding is possible when using the correct shielding gas blends, welding process and welding parameters.
STORAGE
Welding wire should be stored in a dry, enclosed environment and in its originally-sealed package.
