Is anyone familiar with shielding gas filters? I'm trying to find in-line type filters that I can hook up once the gas has passed through the regulator. I'm finding very fine filters, like .02 or .01 micron, but I feel that is a bit excess for my requirement. In reality, I'd like to find one filter around 60-80 micron and another between 5-10 micron. Brass material is preferred. Does anyone have any suggestions on types of filters or at least where I can look to find some filters?

It is a requirement of a code that I work to. It would be used on shielding/ trailing/ purging gas for TIG and FCAW processes.Comment

Interesting, are you welding on a refractory metal? I would be interested to know what kind of components you're working on. If they are asking for this requirement, I would have guessed that the spec would call out a specific filter and the supplier, but obviously that isn't the case here.Originally posted by ksm2 View PostComment

Swagelok makes several filters in both brass and stainless.
Here are 2 home made trailing shields.

Thank you for the help! I was able to find a brass filter in my continued research, but I just realized I'm also in need of a fiber filter which I have yet to see any of this style filter. Any suggestions?Comment

May sound like a nutty approach... but..Originally posted by ksm2 View Post
Have you considered using a clear inline fiber fuel filter like a FRAM G3HC..??
should be well within the working pressure range for argon...
