Dear Mr. Sankalp,
As per AWS 5,32 following shielding gases are used for various metals.
AWS SG- AO -2 ----- 98 Ar + 2 % O2 is used for SS
AWS SG- A ----- 100 Ar for Aluminum (or)
AWS SG- He A-25 ----- 75 He + 25 % Argon for Aluminum (or)
AWS SG- AHe-10 ----- 90 Ar + 10 % Helium for Aluminum.
AWS SG-C ----- 100 CO2 for Carbon Steel (or)
AWS SG- AC-20 ----- 80 Ar + 20 % CO2 for Carbon Steel (or)
AWS SG- ACO -8/2 ----- 90 Ar + 8 CO2 + 2 % O2 for Carbon Steel.
Other mixture gas ratios are also available for CS but, above are generally recommended.
C Sridhar.

Please comment on the weld metal properties of GMAW welded ASS with shielding gases 98%Ar+2%O2 and 98%Ar+2%CO2. How a shielding gas among these two will be selected.
Regards,
Sankalp
