- Applications
- It is designed for welding of 590MPa high tensile steel with outstanding mechanical properties.
Typical applications include machinery, shipbuilding, offshore structures, bridges and general fabrications.
- Characteristics on Usage
-
- - It is a rutile type flux cored wire for all-position welding with 2.0% Ni component.
- - It feature excellent mechanical properties, easy slag removal, low spatter generation, smooth bead shape and high X-ray safety.
- 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.
- Sizes Available and Recommended Currents ( DC +)
