Application
ERNi-1 (NA61) is used for GMAW, GTAW and ASAW welding of Nickel 200 and 201, joining these alloys to stainless and carbon steels, and other nickel and copper-nickel base metals. Also used for overlaying steel.

Note:  Other shielding Gases may be used for Tig welding. Shielding gases are chosen taking Quality, cost, and Operability into consideration.
Note:  Both agglomerated and fused fluxes can be used for submerged arc welding.
Note: The chemical composition of the flux mainly affects the chemistry of the weld metal and consequently its corrosion resistance and mechanical properties.
