Recommended Welding Parameters for TIG, MIG, and SAW Welding of Nickel Alloys
Process Diameter of Wire Voltage (V) Amperage (A) Gas
Tig .035 inches x 36 12 – 15 60 – 90 100% Argon
.045 inches x 36 13 – 16 80 – 110 100% Argon
1/16 inches x 36 14 – 18 90 – 130 100% Argon
3/32 inches x 36 15 – 20 120 – 175 100% Argon

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.
