 Print Sheet


CLASSIFICATION: E90C-D2 per AWS A5.28, ASME SFA 5.28

Select 80C-D2 is a composite metal cored electrode for single and multiple pass welding of certain high strength, low alloy steels where a minimum tensile strength of 90,000 psi is required in the deposited metal. This premium electrode provides a productivity-enhancing welding alternative to ER80S-D2 solid wires.

APPLICATIONS: Select 80C-D2 is perfect for those applications requiring weld metal which matches the mechanical properties of high strength, low alloy pressure vessel steels such as ASTM A302, GrB and HSLA steels and manganese molybdenum castings such as ASTM A49, A291 and A735.

DIAMETERS: .035", .045", .052", 1/16"

SHIELDING GAS: 75-95% Ar/balance CO2, 40-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Smooth, low spatter spray transfer.
  • 30-50% faster travel speeds than corresponding solid wires for greater productivity.
  • Elimination of cold lap.
