CLASSIFICATIONS: E91T1-Ni2C, E91T1-Ni2M per AWS A5.29, SFA 5.29

Select 910-Ni2 is designed for single and multiple pass welding, in all positions, of certain low alloy steels and steels with low temperature CVN properties.

APPLICATIONS: Select 910-Ni2 is a fine choice for welding steels requiring low temperature charpy v-notch toughness, such as the fine grained ASTM A516, A517 and A572 grades, as well as the nickel bearing steels, such as ASTM A203, GrE, A302 and A633. These steels are used in the fabrication of earthmoving machinery, mining equipment and oil storage tanks.

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

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

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Good low temperature toughness.
  • Smooth spray transfer with minimal spatter.
  • Fast freezing slag promotes all position welding.
  • Produces weld beads with excellent profile and minimum convexity.
