DETAILS
The weld metal can withstand a normalizing heat treatment (900°C/4H) and still comply with the minimum mechanical requirements of S355 material grades. This wire provides significant value for welded parts such as flanges or pressure vessel heads that need a normalizing heat treatment after a high level of plastic deformation. When using this wire, welding can be executed prior to the normalization treatment and thus, the additional PWHT is avoided.
Features
- High resistance to porosity
- High resistance to porosity
- Mechanical properties after normalizing meet base material requirements
Typical Applications
- Wind tower
- Welding of wind tower door frames.
- The Outershield MC420N-H is designed to be used only in the normalized condition. As neither AWS nor EN has included weld metal properties in the normalized condition, the wire cannot be classified for the condition it is designed for.
Welding Positions
- All positions
Shielding Gas
- M21 : Mixed gas Ar+ 15-25% CO2, Gas flow : 15-25l/min
