Avesta LDX 2101 is a TIG rod for welding duplex and superduplex stainless steels. It works on chemical installations, desalination plant, tanks and offshore structures in two phase steels.
The rod suits grades such as 1.4301 and AISI 304. It covers root runs, thin walls and welds that need a smooth face, and it is used in the chemical, paper and marine industries on parts loaded both mechanically and by corrosion.
- Classification EN ISO: W 23 7 N L
- Diameters: 1.2 / 1.6 / 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.
