AWS A5.4 : E310
▶︎ Characteristics:
Good corrosion-resistance against acetic acid and its anhydride, hot contaminated sulphuric and phosphoric acids and other contaminated oxidizing mineral acids. Intermetallic precipitation is widely prevented.
▶︎ Applications:
For joining materials of the same and similar nature, e.g. material-no. 2.4602 (NiCr21Mo14W / UNS N06022) and special stainless steels. Furthermore it can be used for dissimilar joints of these alloys with low-alloyed materials and cladding
▶︎ Notes on Usage:
1. Dry the electrode at 350-400°C for 60 minutes before use.
2. Keep the arc as short as possible.
3. Crater should be ground smooth or crater treatment.
