- Applications
- WT-439 is a metal cored wire designed for flat and horizontal fillet welding of AISI 439 ferrite stainless steels.
- Characteristics on Usage
-
- - WT-439 is a metal cored wire for high speed welding.
- - This wire gives excellent bead appearance and provides the operator with a soft stable arc and very low spatter levels thus giving enhanced cosmetic appearance.
- - It has the high tensile strength at the high temperature atmosphere.
- Notes on Usage
-
- - The shielding gas should be used Ar+2%O2 for welding.
- - Gas flow rate is proper 20~25ℓ/min.
