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
	1/8 inches x 36	15 – 20	150 – 220	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.
