There are also many accepted procedures in which welds overlap.Pipeline circumferential welds cross the longitudinal seam welds,and pressure vessel nozzles cannot always be added in regions free from fabrication butt welds.Welding Propane Tanks [Be Carefull!!] Hearth ForumsMay 09,2013 welded aluminum storage tanks total circumferential force#0183;My experance with welding these tanks [I,m still alive] I have welded all my life but I should have checked into this I guess.I got an old propane tank,was around 85 to 100 Gal.short fat one,I took gauge and top valve out looked inside was empty,still smelled bad.
