I'd bet most air tanks are welded by computerized robotics.
I'm a home garage guy. A trick I learned years ago: Since my tank is going to leak down between uses anyway; when I bought my new compressor I set the drain to leak just a little. So, any moisture always gets pushed out. Since I couldn't hear a small leak, I used soapy water in a paper cup and just opened the drain til I got bubbles. Works fer me and YMMV.RETIRED desk jockey.

And yes portables are required as well as long as they are over ten gallons.
And I didn't go out of my way to learn this crap just because I have all this free time and no life I managed a maintenance shop for a large company.(100 employees and three shifts) I not only took care of all the facilities machinery and production machinery. I also had to take care of all the licenses, permits, and inspections too. Fire dept, Health dept, Cal Osha, CARB, Cal state water resources board. EPA. etc were all on my list of people that would pay me a visit every few months to at the very minimum once a year with follow up visits to prove compliance.

Funny that folks are all nuts about a US welder making a tank to a way overbuilt spec but we think little of imported Chicom tanks that are made by who knows under what process control. Sure the first one was inspected and passed but how about the ones made when no one is looking which are most of them. They can't even keep lead out of paint or dog food and raw material for medicine clean, what makes anyone think that are using good methods, metal and filler to make pressure tanks?Weekend wannab racer with some welders.

making pressure tanks/etc/etc than just running a few quick beads
on some scrap that was laying around (i'm being a bit snarky just
to emphasize the point -- the original poster definitely was not
proposing such a bit of cruftsmanship).
reading the thread has reinforced my view that, as a weekend
weldor, there's no way in the netherworld that i'd want to take
on a job like this by myself. i'm fairly sure i'd blow myself up...
presumably, the original poster can use this information the same
way as i did, to decide what he'd overlooked, how to deal with it,
and so on.
some folks mentioned cost effectiveness. it may not be cost
effective to make your own tank -- but it might be a lot more fun
and give you a lot more satisfaction at the end of the day. as the
master card ad says, "priceless".

Willy, Nice looking comp.
There are prob 100 guys on this forum that could weld up a tank, but with out the ASME stamp someone will be asking for trouble some day if something ever happened not saying it will. I have had 2nd thoughts about using mine that i scabbed together from a semi truck air tank that is prob 35 years old. I think its time to replace the tank with a store bought one and use my old one for an oil drum or something...BobBob Wright, Grandson of Tee Nee Boat Trailer Founder

He built one for himself, myself, my brother, my brother-in-law, and one of his close friends. I've got to take it all apart to clean it again one of these days - I'll get some photos and post them - with a disclaimer of course "Don't try this at Home"
