Avesta 2507/P100 is a TIG rod for welding duplex and superduplex stainless steels. It goes into tanks, pipelines and chemical or marine structures that need strength and corrosion resistance at the same time.
TIG gives you full control over the heat input and a clean, smooth weld, which makes the rod a fit for root runs. It is used in the chemical, paper and marine industries, on parts loaded both mechanically and by corrosion.
- Classification EN ISO: W 25 9 4 N L
- AWS classification: ER2594
- Diameters: 1.2 / 1.6 / 2.0 / 2.4 / 3.2 mm
Watch the heat input and the interpass temperature, overheating duplex upsets the balance between ferrite and austenite in the weld. Set the gas post-flow long enough for the pool and the electrode to cool under the shield. Grind the tungsten tip along its axis and hold a short arc, otherwise the pool spreads. Thinner diameters suit root runs and thin sheet, thicker ones suit filling.
