A few weeks ago I opened the topic "Building a statue out of a super austenite".
It said that we should use
MIG
welding, as TIG is out of the question..
In the case of the statue, the inert gas will inevitably remain inside.
Dense weld seams can be delivered with any welding process if they are carried out thoroughly.
This is due to the skill of the welder.
Wouldn't MIG then also be suitable for this project?
Since we get Argon 6.0 for free anyway.
The donation to the forum has not yet been forgotten.
I am asking here because the Russian welding company is getting more and more entangled in contradictions ...
Then you could use the purest argon and then would not have any reactive gases such as oxygen or carbon dioxide inside.
I have only read about the fact that with the MAG process, the weld seam is probably a little more stable, i.e. it has better contact with the material.
But the statue is not a highly stressed component.
The question would also be, is the shielding gas used up during welding?
In other words, if I do MAG welding and there is an argon / oxygen or argon / CO2 mixture, is the oxygen or the O2 completely consumed?
I have also read that with MAG you use oxygen instead of CO2 if you want the seam to be of even better quality.
A deeper penetration etc.
On the other hand, it would be more stable with CO2 because more carbon diffuses into the weld seam.
In a pinch, if only MAG works, we would order a mixture of ARGOn and oxygen.
But we would prefer MIG.
Large sheet thicknesses of 30 mm or more can be welded with MIG and MAG.
Above all, it is important that the weld seam is as tight as possible.
Would we prefer TIG?
Wouldn't that work ???
