 Print Sheet


CLASSIFICATION: E110T5-K4C per AWS A5.29, ASME SFA 5.29

Select 115-K4 is a basic electrode designed for welding certain low alloy steels where a minimum tensile strength of 110,000 psi and good low temperature notch toughness are required.

APPLICATIONS: Select 115-K4 produces a tough, high strength weld metal that is resistant to cracking in highly restrained joints. These characteristics make it an ideal selection to weld high strength, low alloy steels such as T-1, HY-100, ASTM A514 and others of similar strength.

DIAMETERS: 1/16", 3/32"

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Better mechanical properties than rutile slag systems.
  • Outperforms typical T-5 electrodes.
  • Similar slag removal and bead geometry to E10018 electrodes.
