• Applications
  • It is designed for welding of 490MPa high tensile steel with outstanding mechanical properties. Typical applications include machinery, shipbuilding, offshore, offshore structures, bridges and general fabrications.
  • Characteristics on Usage
    • - It is a metal cored wire for flat and horizontal position welding.
    • - It has good porosity resistance and is applicable for fillet welding of inorganic zinc-primer coated steels.
  • Notes on Usage
    • - Proper preheating (50~150°C) (122~302° F) and interpass temperature must be used in order to release 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.
