- Applications
- Pumps, valves, pipework and vessels for use in aggressive environments in chemical process plants, also in equipment for flue gas desulphurization and critical equipment in offshore oil and gas production.
- Characteristics
-
- - It can be used for surfacing steels and dissimilar welding of nickel alloys, steels and stainless steels.
- - The weld metal has excellent resistance on pitting and crevice corrosion.
- Notes on Usage
-
- - Use recommended current range. if not it will be much spatters and undercut.
- - Keep the arc as short as possible.
- - Weaving width should be within two and a half times electrode's diameter.
- - When the electrodes have absorbed moisture, dry them at 250~280℃ for 30~60 minutes before use.
