 Print Sheet


CLASSIFICATION: E80T5-Ni3M per AWS A5.29, ASME SFA 5.29

Select 85-Ni3 is a low alloy, gas-shielded, flux cored electrode for single and multiple pass welding of certain HSLA steels. It provides a weld deposit that contains about 3.5% nickel to enhance low temperature toughness.

APPLICATIONS: Select 85-Ni3 is designed to weld 3% nickel steels that require a postweld stress relief, a minimum of 80,000 psi tensile strength and excellent low temperature toughness. Applications include shipbuilding and tanks used for gas storage.

DIAMETERS: .045", .052", 1/16", 5/64", 3/32"

SHIELDING GAS: 75-80% Ar/ balance CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Basic slag system provides excellent low temperature toughness.
  • Produces low diffusible hydrogen levels.
  • Arc transfer is globular and the bead profile is convex.
