Slightly OT - welding tank wall thickness?

admin

Hi guys, I've got a project under way that involves using an old welding tank. I need to make sure of the interior dimensions--does anyone here know the general wall thickness on a typical welding tank (9" diameter)?Thanks in advance.-Mike
Reply:That is a moving target.  The wall thickness will depend on a number of variables such as alloy, method of manufacture, intended use or application.  To just say "welding tank" may present a picture in one's mind, but that description is more nebulous than you may think.How close an estimate do you require?-mondoMember, AWSLincoln ProMIG 140Lincoln AC TombstoneCraftsman Lathe 12 x 24 c1935Atlas MFC Horizontal MillCraftsman Commercial Lathe 12 x 36 c1970- - - I'll just keep on keepin' on.
Reply:The thickness varies, being greater at the top and around the bottom but was about 1/4 inch for a medium, old oxygen tank I made something from a few decades ago, IIRC.
Reply:Thanks guys - as I continue to do followup research on my own I'm realizing that this is indeed a question with a ton of variables.One thing that we just noticed is that the initial test date stamped on the side is 1952, and the final date is 1996. The stories this tank must have to tell!I did a more precise measurement, the outside is 9.25" diameter. We're hoping to have something slightly larger than 8.5 inside, so Oldiron2, your information would mean we're in good shape...
