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.
