- 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.
- Sizes Available and Recommended Currents ( DC +)
