Recommended Welding Parameters for MIG and SAW Welding of Nickel Alloys
Process Diameter of Wire Voltage (V) Amperage (A) Gas
MIG .035 inches 26 – 29 150 – 190 75 % Argon +25% Helium
.045 inches 28 – 32 180 – 220 75 % Argon +25% Helium
1/16 inches 29 – 33 200 – 250 75 % Argon +25% Helium
SAW 3/32 inches 28 – 30 270 – 350 Suitable Flux May Be Used.
1/8 inches 29 – 32 350 – 450 Suitable Flux May Be Used.
5/32 inches 30 – 33 400 – 550 Suitable Flux May Be Used.

Note: Other shielding Gases may be used for Mig 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.
