- Applications
- Main uses are for the applications of resistance to heat and corrosion and for the joining of stainless steels to mild or low alloy steels.
- Characteristics on Usage
-
- - WT-309MOL 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.
- - Weld metals contain comparatively much more ferrite in their austenitic, therefore they provide better weldability together with superior heat resistance, and corrosion resistance.
- Notes on Usage
-
- - The shielding gas should be used 100%CO2 or Ar+20~25%CO2 for welding.
- - Gas flow rate is proper 20~25ℓ/min.
