CLASSIFICATION: E110T5-K3C per AWS A5.29, ASME SFA 5.29

Select 115-K3 is a basic low alloy steel, gas-shielded, flux cored electrode for horizontal fillet and flat position welding of certain HSLA steels. This electrode is capable of single and multiple pass welding. The arc transfer is globular with a convex bead profile due to the nature of a basic slag system.

APPLICATIONS: Select 115-K3 produces weld metal with a minimum tensile strength of 110 Ksi, excellent low temperature CVN toughness and low diffusible hydrogen levels. These characteristics make 115-K3 an ideal selection for welding high strength, low alloy steels such as T-1, ASTM A514 and HY-100.

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

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Basic slag provides low diffusible hydrogen and excellent CVN toughness.
  • Meets the same requirements as E11018-M covered electrodes.
  • Well suited for welding HSLA steels in the 110-130 Ksi tensile range.
