- Applications
- WT-309H is designed for the welding of dissimilar metals such as stainless steels and carbon steels or stainless steels and low alloy steels.
- Characteristics on Usage
-
- - WT-309H is a rutile type flux cored wire for all-position welding.
- - It provides the excellent usability with stable arc, less spattering, good bead appearance, better slag removal, and less quantity of welding fume comparable to solid wire.
- - The weld metal contains optimum ferrite contents in their austenitic structures, Therefore their weldability is excellent with lower crack susceptibility.
- Notes on Usage
-
- - The shielding gas should be used 100% CO2 and Ar+20~25%CO2 for welding.
- - Gas flow rate is proper 20~25ℓ/min.
- Sizes Available and Recommended Currents ( DC +)
