CLASSIFICATIONS: E80T1-Ni1C per AWS A5.29, ASME SFA 5.29
Select 81-Ni1 is a gas-shielded electrode intended for single and
multiple pass horizontal fillet and flat position welding of carbon
and low alloy steels requiring a minimum tensile strength of 80,000
psi and good CVN toughness at subzero temperatures.
APPLICATIONS: Select 81-Ni1 is the ideal selection for welding
steels combining moderate tensile strength and excellent CVN toughness,
such as ASTM A572 Gr60, A302, A575, and A734. These steels are used
in mining machinery, offshore platforms, shipbuilding and earthmoving
equipment.
DIAMETERS: 1/16", 5/64", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
