Welding-nickel-tables report selected designations and approximate nominal compositions of useful Nickel Alloys.

For exact limits and requirements refer to the official AWS documents.

See also Welding Nickel.

Tables include welding consumables for highly corrosive environments.

Also for applications with the most severe corrosion resistance requirements.

These filler metals are used for welding nickel base alloys and fully austenitic stainless steels.

In severe service conditions, extreme heat, corrosion, abrasion, high pressures and combinations of these conditions are present.

Welding-nickel-tables of Consumables

Good quality, consistent consumables are necessary for the most demanding applications.

The higher alloyed NiCrMo and NiCrFe types display both notch toughness at -196ºC and good resistance to oxidation and creep at temperatures up to 1000 ºC.

The NiCrMo and NiCrFe types are also well suited to weld steel plate clad with nickel based alloy or stainless steel.

NiCrMo and NiCrFe consumables are the only suitable options for welding ferritic CrMo steels to stainless steels, if heat and creep resistant properties are mandatory.

The ENiCrFe-3 electrode is fit to repair high carbon cast steel components, particularly when PWHT is needed.

It can tolerate high dilution and provide matching strength levels.

Also ductility and toughness are not impaired by such heat treatments.
