- Applications
- Welding of such parts, where the highest reliability is required, such as strength members of ship hulls, high pressure vessels and buildings.
- Characteristics
-
- - W 4301 is ilmenite type covered electrode which is designed for better weldability in particular.
- - Welding of such parts, where the highest reliability is required, such as strength members of ship hulls, high pressure vessels and buildings.
- - W 4301 is lime-titania type electrodes for all-position welding, which has excellent usability. Its crack resistibility and X-ray soundness are excellent.
- - The most excellent mechanical properties and also suitable for welding of structural steels of heavy section about 25mm thickness.
- Notes on Usage
-
- - Pay attention not to exceed the range of proper currents in case of welding structures which require weld metal of high X-ray soundness.
- - Dry the electrodes at 70~100℃ for 30~60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosities.
- - Excessive drying before use causes less penetration and overheating of the electrode.
