Select 810-Ni1 Close Window
 Print Sheet


CLASSIFICATIONS: E81T1-Ni1C/E81T1-Ni1M per AWS A5.29, ASME SFA 5.29

Select 810-Ni1 is intended for single and multiple pass, all position welding on carbon and low alloy steels requiring good CVN toughness at subzero temperatures and tensile strength in excess of 80,000 psi.

APPLICATIONS: Typical steels welded with Select 810-Ni1 include ASTM A572, A302, A588 and A734. These steels are used in the fabrication of transmission poles, light poles, earthmoving and mining machinery and offshore platforms.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: 100% CO2, 75-80% Ar/balance CO2, 35-50 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Good low temperature toughness.
  • Spray-like arc transfer with very little spatter.
  • Fast freezing slag facilitates welding in all positions.
  • Moderate slag volume with easy removal.
