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.
