• Applications
  • WT-131K4C is designed for low alloy, high tensile steels where welds of 120 ksi (830MPa) minimum tensile strength are required.
    Typical industrial applications include shipbuilding, machinery, piping, bridge, structural fabrication and building.
  • Characteristics on Usage
    • - It is a rutile type flux cored wire for all position welding.
    • - It provides smooth arc, low spatter levels, good weldability and good bead appearance.
    • - Wire with very low amount of diffusible hydrogen.
  • Notes on Usage
    • - Proper preheating(130~160°C) and interpass temperature must be used in order to release diffusible hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates.
    • - Gas flow rate is proper 20~25ℓ/min.
    • - Shielding gas should be used 100% CO2.
