This is a 18 wheeler truck tank. I purged it with argon and started welding it but I dont like what I am seeing so fuck it. I dont need to die today.

Try welding on a natural gas line.....as long as no oxygen inside the pipe, no problems.

More fun doing the welding in a ditch or pit....that gets fill with gas. Like a match, throw it in the hole, whoosh!......roll in and start welding.

Welding torch's burn a little hotter then a match. ;)

Also I have started a number of number of campfires with a little diesel and a match.

Post by: Passenger on November 01, 2009, 04:33:39 PM: I've welded lots of diesel and gasoline tanks, clean them out real good with soapy water or a detergent that removes oil, leave the cap open, and weld away.

He's not welding a tanker he's welding a saddle tank. If he can fit through the filler cap he has bigger problems than welding up that crack.
