• Applications
  • WT-100K3 is designed for welding of 690MPa high tensile steel for low temperature service.
    Typical applications include pipe line, wear resistance steel such as API 5L, X70, X80, EN 10208-2 L480, L550, EN 10137-2 S550, S620.
  • Characteristics on Usage
    • - Wire is a titania type of flux cored wire for flat and horizontal position welding.
    • - It provides smooth arc, low spatter levels, good weldability and good bead appearance.
  • 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.
