Avesta 2205 is a submerged arc (SAW) wire for welding duplex and superduplex stainless steels. It is used in the chemical, paper and marine industries, on parts loaded both mechanically and by corrosion.
The wire suits grades such as 2205 and 1.4462. It works as a set with a matched flux, which decides the mechanical properties of the weld.
- Classification EN ISO: S 22 9 3 N L
- AWS classification: ER2209
- Shielding: flux matched to the wire, no shielding gas
- Diameters: 2.4 / 3.2 / 4.0 mm
Do not quench the joint with water or force the cooling, too fast a cooling rate leaves too much ferrite in the weld. Match the flux to this wire and check how dry it is, drying the flux decides the hydrogen level in the weld. Keep an even flux layer over the arc, too thin a layer exposes the arc and too thick a one spoils the bead shape. Thinner diameters suit root runs and thin sheet, thicker ones suit filling.
