Bohler Avesta 2205-PW AC/DC (Duplex) Stainless Steel Stick Electrodes
Avesta 2205 Autile coated electrode of E 22 9 3 N L R / E2209-17 type. Primarily designed for welding 22Cr duplex stainless steels such as 1.4462 / UNS 31803 used in offshore, shipyards, chemical tankers, chemical/petrochemical, pulp and paper, etc. Good weldability in all welding positions. Very good resistance to pitting and stress corrosion cracking in chloride containing environments. Good wettability and slag detachability result in smooth and clean welds.
Features
- The "PW" designation highlights its tailored design for positional pipe welding, providing a highly stable arc and superior control when welding out-of-position.
- Highly resistant to pitting and stress corrosion cracking (SCC) in aggressive, chloride-bearing chemical and marine environments.
- Features a rutile-based coating that ensures effortless arc striking, excellent wetting behaviour, a smooth weld bead profile, and easily removable or self-detaching slag
