- Applications
- It is designed for welding of 490MPa high tensile steels with Ar+20%CO2 shielding gas.
Typical applications include railcar, automotive machinery, shipbuilding, bridges, heavy equipment etc.
- Characteristics on Usage
-
- - It is a rutile type flux cored wire for all-position welding.
- - It features excellent mechanical properties, easy slag removal, low spatter generation.
- - It is designed good impact value at low temperatures down to -40°C in PWHT conditions.
- 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.
- - One-side welding defects such as hot cracking may occur with wrong welding parameter such as high welding speed.
- - Gas flow rate is proper 20~25ℓ/min.
- - Shielding gas should be used Ar+20~25%CO2.
