Re: [MW:31053] How to check Argon Gas Purity?

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 & WPS

Thanks & Regards

Normally you can get the Test certificate from the gas supplier about the purity of the gas.

Its enough to confirm the purity for WPS requirements.

Mr.Prabhu,

You can check with Argon gas meter / Analyzer for 99.9 % purity or as per WPS requirements. Hope it's clear.

You want to check which impurity?

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.
