Application
ERNiFeCr-2 (NA718) filler metal is used by gas tungsten arc welding process for Cr-Ni-Nb-Mo alloys. Use of high heat impart process such as mig often results in micro-fissuring.

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.
