- Applications
- Butt and fillet welding of steel structures and using 550MPa or 600MPa tensile steels such as construction machinery, buildings and pressure vessels.
- Characteristics on Usage
-
- - WM-80 is a solid wire for flat and horizontal fillet welding position. As the deposition rate is very high, highly efficient welding can be performed.
- - As this wire contains special elements, its weldability and impact values are excellent.
- Notes on Usage
-
- - Shielding gas should be used 100%CO2.
- - Use wind screen against wind.
