- Applications
- WT-308L(P) is designed for the welding of low carbon 18% Cr-8%Ni stainless steels.
- Characteristics on Usage
-
- - WT-308L is a rutile type flux cored wire for flat and horizontal position welding.
- - WT-308LP 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 or Ar+20~25%CO2 for welding.
- - Gas flow rate is proper 20~25ℓ/min.
