• Applications
  • WT-111K3 is designed for welding of 760MPa high tensile steel with outstanding mechanical properties.
    Typical applications include high tensile steels that will be used a low temperature environment.
  • 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.
    • - It provides excellent impact values at low temperature.
  • Notes on Usage
    • - Proper preheating(50~150℃) 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.
