To be honest MIG welding stainless isn't going to look that pretty, particularly on thinner material, unless you use a pulse machine
How suitable would Pureshield Argon be for stainless?
I read the best gas is 2.5% co2, argon....any higher co2 is unsuitable....why is that? What does the 2.5% do?
Cheers
High quality stainless steel welds are perfectly achievable with MAG but you have to be correctly geared up for it and posses the necessary skill setsI have always considered stainless welds to be Either:-
A, Fast & Functional (Non Cosmetic) = Mig
B, Slow, High Cost & pleasing to the eye = Tig.
Used to do a lot of stainless pipe mainly low pressure 1" up to 6" with Mig using Stainshield Universal the helium helps but they never looked nice but once fitted within days they were caked with black paint an resin, so the only criteria was economical functional welds.
The odd emergency welds done with standard argosheild always had a slightly higher rounded cold looking bead profile.
Is this for a odd job or a ongoing process?
Would the material be thick enough to weld with a stick in MMA, that way you should get a nice looking weld at little cost.

It doesn't need to look amazing, but still shiny
what kind of welder do you think was used here? View attachment 109577
My mig is 250amp...what is the ideal set up for what I want to do?

Sorry I thought it was a jokeSee...I have low standards!
So...properly set up mig would produce better results than the pic?
Sorry I thought it was a joke
Think it's been gobbed together with MIG but a bit hard to tellnope...no joke, never welded stainless, wondering what's likely been used to do the weld in the pic
If memory serves me yes I think that's what we did before argoshield first came out for mig, of course we have the Staindhield? now never used it (many years since I did stainless but did stacks in the late 80s and early 90s, seemed everything had to be stainless then for a while)Will pure CO2 weld stainless?
Not really, yes it may stick it together but the oxidation will be horrendous plus you'll have massive carbon pick up so you will have a joint that corrodes like hell and the mechanical strength will be compromised, if those factors aren't an issue you will get away with itWill pure CO2 weld stainless?
Ah not practical then.Not really, yes it may stick it together but the oxidation will be horrendous plus you'll have massive carbon pick up so you will have a joint that corrodes like hell and the mechanical strength will be compromised, if those factors aren't an issue you will get away with it
