Dear ,In SFA 5.32 which gives the requirements for shielding gases, the requirement is to mention % composition to check if it is a single gas or mixed gas. So the code is not asking about the purity of the gas.Purity of the gas is mentioned seperately as 99.997 %. This is more of a procurement parameter rather than welding.As per my opinion, one should mention the percentage composition of the gas rather than purity in the wps format.Regards,Charles V Jacob.--On Sun, Jun 28, 2020, 7:31 AM 'james gerald' via Materials & Welding <materials-welding@googlegroups.com> wrote:--The reason for having purity % in WPS is to check whether you use Single or mixture of gases which is an essential variable. Welding Grade Argon purity as per ASME Sec.IIC is 99.997%. In addition to this for Duplex & SDSS we mention the Oxygen ppm levels in the PQR & WPSThanks & Regards

Normally moisture/dew point need to be checked as per AWS 5.32. It should be less then 10.5 ppm.
To check moisture, dew point analyzer is available.
