- Applications
- WT-307P is designed for welding dissimilar steels, 13% Mn steels with reduced weldability and for cladding carbon steels.
- Characteristics on Usage
-
- - 307P is a rutile type flux cored wire with a hot cracking resistant austenitic weld metal.
- - The weld metal has an excellent crack resistance, even when welding steels with very poor weldability.
- - This wire is designed for welding dissimilar steels, 13Mn steels with reduced weldability and for cladding carbon steels. Can also be used as a buffer layer prior to hard surfacing.
- Notes on Usage
-
- - The shielding gas should be used 100%CO2 or Ar+20~25%CO2 for welding
- - Welders for solid wire can be used but as wire is softer than solid wire, pay full attention
to adjust feeding roller and do not tighten them excessively.
