has you ever seen one before?

i was just wondering if it has ever been done.  i could make me one but don't want to spend the money lol,  i think a stainless tank would be cool.  i'm a boilermaker, so all my stuff i weld gets pressure tested or x-ray tested.  we use tri-mix for all of our stainless. 

what grade do you normally work with? we mostly do standard 304 and can get away with the 75/25 on it. but anything high pressure related, appearance, or odd grades we use the tri (helium, argon, co2). I did a repair on chemical container one time that was some weird ass grade. had to keep changing tungstens and gasses to get it to flow right. it kept forming a layer of like a flux over it and the stuff would literally begin shooting off as it cooled and would hit me in the face and eyes. then once we got the right combination of gas and tungsten it welded out, but it still didn't flow real well. the weld looked weird too. but it didn't leak and it was a rush job so it did what it had to

we use just about everykind, depends on what the customer wants,  i think i welded on the same stuff you are talking about,  it didn't want to flow and the bead kept acting like it was cold and would melt in or like it kept hitting hard and soft spots all threw the metal and it would have a thin coating of stuff just like flux.  i didn't like it lol was a bitch and it was a damn huge ass tank to, took like 3 weeks of 10hr days to weld.  and i did a damn awesome oil tank once that was about 10 ft tall and like a 5 ft diameter, the tank was ss and was about 30k dollars, and then they put damn carbon legs on it out of 3x4 L  i was like dumbasses.  nice tank with rotted legs in about 15 years lol, i hate using 309 to weld stainless and carbon together.

Publix tends to do stuff like that on occasion. and just about everything they deal with is highly corrosive, so we just have to go back and redo some of it a few years down the road. the airport on the other hand, they don't care what it costs, they want it done right. it costs less to build a fuel container properly than to pay a settlement from a death from a faulty tank
