Can I weld a used oil tank?
Can I weld a used oil tank?
(OP)
My question is whether or not it is safe to weld a used oil tank. I have read several methods that have been used to do this but almost all of them sound like back woods style and unsafe. Any suggestions on how this can be accomplished safely? Are there any published codes and/or documentaion on safe methods?
Thanks for the help

Even then, if you're like me when you first strike the arc you're waiting for the big bang. What I usually do for a bit of extra insurance is to flood the inside of the tank with a C02 extinguisher, this will displace the oxygen. I've also heard of people using dry ice (C02), put a piece of it inside the tank for awhile and it will also dissipate the oxygen.
You said a used oil tank, granted oil is not as flammable as gas but who says noone didn't dump a little in there, plan for the worst case, my opinions only, take them for what they're worth....Mike

A method I have used in the past is to fill the vessel COMPLETELY with water, turning it so where the cutting or welding has to be done is at the very top. As you cut into the vessel as small amount of water would run away(meaning the vessel was full) I believe this is now not allowed. As Mike says the only sure way is to have the vessel purged completely of all residues AND then checked by a competent technician.
