BÖHLER ER 80 S Ni 1-IG is a TIG rod for welding low-temperature nickel steels. It is used on liquefied gas tanks, cryogenic installations and refrigeration equipment.
TIG gives you full control over the heat input and a clean, smooth weld. The rod suits root runs, thin walls and welds that need a smooth face.
- Classification EN ISO: 636-A W Z2Ni1Mo
- AWS classification: A5.28 / SFA-5.28 ER80S-Ni1
- Shielding gas: I1
- Diameters: 1.0 / 1.2 / 1.6 / 2.0 / 2.4 mm
Run narrow beads without wide weaving, so the weld keeps its fine grained structure. Keep the rod inside the gas shield even after you lift it from the pool, a cold oxidised end will contaminate the next drop. Set the gas post-flow long enough for the pool and the electrode to cool under the shield. Thinner diameters suit root runs and thin sheet, thicker ones suit filling. A change of shielding mixture changes how the arc behaves, so try it on a test piece before production.
