UTP A 068 HH is a TIG rod for welding nickel alloys. It goes into tanks and pipework made of nickel alloys, and into cladding layers on steel.
TIG gives you full control over the heat input and a clean, smooth weld, so the rod suits root runs and thin walls. It works on boiler components, furnace parts, chemical installations and heat exchangers exposed to aggressive media.
- Classification EN ISO: S Ni 6082 (NiCr20Mn3Nb)
- AWS classification: ERNiCr-3
- Diameters: 1.6 / 2.0 / 2.4 / 3.2 mm
Keep the interpass temperature low and limit weaving, nickel is prone to hot cracking. Protect the root when you weld from one side, an oxidised underside spoils the corrosion resistance. Keep the rod inside the gas shield even after you lift it from the pool, a cold oxidised end will contaminate the next drop. Match the diameter to the material thickness and the welding position, thinner rods are easier to control out of position.
