 Print Sheet


CLASSIFICATION: ECNi2 per AWS A5.23, SFA 5.23.

Select Ni2S is a metal cored, low alloy steel electrode for submerged arc welding only. This wire contains 2-3% nickel to produce good, low temperature toughness.


APPLICATIONS: Select Ni2S is designed for applications involving the welding of carbon and certain low alloy steels where low temperature toughness is required. These include offshore oil equipment, shipbuilding and other cold weather, structural applications.


DIAMETERS: 5/64", 3/32", 1/8", 5/32"

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Provides good low temperature toughness.
  • Offers better control of bead penetration than solid wire.
  • Decreases the tendency for burn through on root passes or poorly fit up joints.
  • Produces higher deposition rates than solid wire.
