I'm reviewing some documents reporting 100% pure CO2 as shielding gas for FCAW welding of P22 pipes.
Is this shielding gas suitable for P22 welding?
If not (as I think), is it not suitable at all or just not recommended?
Which gas mixtures are recommended?
As far as I know, gas mixtures (Ar-CO2) with 2,5% CO2 max should be used for Cr-Mo steel with Cr content above 2%.
