Your English is MUCH better than my Romanian, so no worries...you express yourself just fine.
There is not much to be gained by examining the welded ends, far too many variables.
Are you familiar with F=P*A ? The weld holding your end plug is holding approximately 1719lbs of force (781Kg) at 1000Psi/6895Kpa.
About the best thing to do is what Mr Foo recommended... do a hydrotest on it. Paintball, scuba and scba tanks are taken to 5/3 of the max service pressure.

i understand you " understand romanian ?
about pressure , i tested various things as airtanks to high pressures, during the years of "constructions" , i mean sort of all kind of tubes, tanks i could find at scrap yard .... just one has blown up a door cuz it flew out from the gun into it at about 30 bar - 1 liter...like a rocket .
i will make another airtank like this one and do the test . i will film it and post it here.
anyhow i just try to replicate a performance with a gun i made a couple of years ago ( i mean 20 m hole to hole groupings shots with airsoft bbs) but i just cant figure out what, why was so accurate ..... spent lots of money on barrels, bbs, scopes, air supply, etc.....
